STATEMENT OF OBJECTIVES (SOO)

TASK ORDER 0003

Engineering Analysis and Design for Fatigue-Life-Enhancing Laser Peening Technologies

(FLPT)

1.0 BACKGROUND: Currently, a variety of engineered residual stress technologies such as cold-working and laser peening (LP) are being utilized for fatigue life extension (i.e. – inspection interval setting) of metallic structure across the USAF fleet. Previous structural implementations of LP adhered to a vendor “best-practices” approach that required massive testing matrices and thus funding and testing. AFRL has developed a set of physics based simulation tools which can reduce the initial LP process design. These tools will be used on a current USAF platform which is entering into a service life extension program (SLEP) and wishes to use LP for a life limiting control point. This task order will provide the engineering analysis and design for AFRL/RQVS model validation, experimental test setup, and execution efforts.

2.0 OBJECTIVE: The objective of this task is to provide the engineering analysis and design necessary to validate the aforementioned analytical physics based toolset, create a usable LP solution, and demonstrate the solution in a structural relevant environment. These tasks will include, but not be limited to: air vehicle and feature level finite element analysis, linear elastic fracture mechanics & strain-life based fatigue analyses, experimental testing fixture design & analysis, test-to-model correlation, material model creation and validation, incorporating pre-existing residual stresses into LP process modeling, and experimental testing.

3.0 TECHNICAL REQUIREMENTS

3.1. TASK 1. TOOLSET VALIDATION

This activity will develop, plan, and execute, in conjunction with AFRL/RQVS personnel, a validation plan for the AFRL LP physical process modelling capability. This will include, but not be limited to: residual stress measurement test matrix creation and execution, material model input data generation, and quantification of sequential cold-working and LP processing on final residual stress state.

3.2. TASK 2. ANALYSIS

This activity will evaluate the stress state of a pre-determined portion of metallic aircraft structure at both the air-vehicle (i.e.-assembly) and feature level length scales. This will include, but not be limited to: evaluation and analysis of provided air vehicle (AV) and feature level finite element method (FEM) models; determination of equivalent test loads for coupon and sub-component loading using the aforementioned FEM models; and support all test-to-model validation activities.

3.3. TASK 3. DESIGN

This activity will utilize all applicable Task 2 results to design specimens and testing fixtures for fatigue testing of un-treated and LP processed specimens. This will include, but not be limited to:

design of coupon and sub-component geometries that reproduce the stress state in the region of interest from the validated AV/feature level FEM models; an experimental testing fixture for the coupon level specimens to be manipulated by a 20-55 Kip load capacity MTS uniaxial servo-hydraulic testing frame; assist in the design of a custom servo-hydraulically actuated sub-component fatigue testing fixture; documentation of all design decisions, supporting analyses;

and technical drawings of all contractor designed specimens and fixturing components.

3.4. TASK 4. TESTING

This activity will assist all testing efforts to be conducted on-site at Wright-Patterson AFB or at an appropriate off-site facility. This will include, but not be limited to: fixturing fabrication, setup, and teardown; thermo-elastic stress analysis of coupons and sub-components for comparison to full-scale fatigue testing articles; on-site data collection, reduction, and documentation at Wright-Patterson AFB during testing; test article material acquisition, coupon fabrication, and residual stress processing of appropriate articles (sub-contracting to an appropriate vendor will suffice).

4.0 DELIVERABLES: The Contractor shall generate and provide data in accordance with the following Contract Data Requirements List (CDRL), DD Form 1423-1:

A001 – Scientific and Technical Reports – Final Report, DI-MISC-80711A/T, One/R

A002 – Scientific and Technical Reports – Spend Plan, DI-MISC-80711A/T, Monthly

A003 – Funds and Man-Hour Expenditure Report, DI-FNCL-80331A/T, Monthly

A009 – Presentation Material, DI-ADMN-81373/T, As Required

A011 – Digital Imaging, DI-MISC-81579/T, As Generated

The contractor shall propose additional deliverables for the TO as appropriate. In addition, software and hardware (including source code, firmware, libraries, and executables) developed under this TO should be delivered with unlimited rights. All software developed under this task order shall be delivered in a format acceptable to both parties. The contractor shall identify any restrictions on the type of rights to be provided with software and hardware delivered but not developed under this TO, with full disclosure of any dependencies upon third party software/hardware.

5.0 FOREIGN PARTICIPATION: Foreign participation is not permitted on this task order.

6.0 PERIOD OF PERFORMANCE: The total period of performance for this effort is 36 months. This corresponds to 33 months of technical effort and 3 months for reporting.

7.0 SECURITY:

7.1. Operations Security. Operations Security (OPSEC) must be an integral part of our daily activities. As we maintain security on our future technologies that are vital to national interest, we must recognize and prepare for the threat poised against our technology. Department of

Defense policies mandate a high degree of security throughout the acquisition process. However, heightened security awareness and threat-based countermeasures are particularly essential during the research and development phase when our technology is most vulnerable to espionage, sabotage, or exploitation. It is the obligation of each employee or persons involved on this contract be constantly aware of and strictly adhere to security requirements designed to protect sensitive unclassified and other information and resources produced by acquisition, research and development, and technological security efforts outlined in this SOO. The contractor shall ensure employees receive training and follow appropriate Operations Security (OPSEC) measures during the performance of the contract.

7.2. Access to classified. All requested personnel for this effort will require at least a Secret clearance (Tier 3).

7.3. Sub-contracting. If the prime contractor sub-contracts work out; the prime contractor must submit a DD Form 254 for all assigned subcontractors within 30 calendar days of establishment of the contract or agreement to the Industrial Security Manager listed on the DD 254. Once an effort is over the contractor and subcontractors must account for all classified hardware and material given, used or generated during this effort. The contractor will submit an encrypted non-classified list of all materials and/or hardware in their position to the Government Contracting

Officer. In the list of items the contractor should outline what items they wish to keep and the justification. The Government Contracting Officer and the Industrial Security Manager will determine if the material will be destroyed or returned back to the government. However, if there is a follow on effort a final DD form 254 must be issued to the contractor authorizing the contractor to retain the classified material, access, hardware for a specified time period.

7.4. Protecting information. The contractor shall not divulge any information regarding files, data, process activities/functions, user IDs, passwords, or other knowledge that may be gained, to anyone who is not authorized to have access to such information. Contractor personnel shall abide by all Government rules, procedures, and standard of conduct. Contractors will require access to Government Automated Information Systems (AIS) and shall have background investigations and security awareness training completed prior to the start of contract performance. When the period of performance is complete and/or contractor personnel leave work on this project, they will have three (3) days to terminate all their network user accounts and to return all access cards and base identification badges.

Contractors shall encrypt all emails containing technical data or other critical information for this program. The use of products such as Encryption Wizard and Amrdec Safe are highly encouraged for safe guarding information when transmitting information via email. Contractors shall comply with DoD 5400.7‑R/Air Force Manual 33‑302, DoD Freedom of Information Act

(FOIA) Program, requirements. Unclassified information not approved for public release on non-DoD Information Systems shall be protected IAW DoDI 8582.01, Security of Unclassified
