Performance Work Statement (PWS) Penetration Mechanics Short Course

10 February 2020

C.1 Background

The Weapons and Materials Research Directorate (WMRD) at the Army Combat Capabilities Development Command (CCDC) requires a course that presents and develops the fundamental and underlying principles of penetration mechanics. The developed fundamental relationships are applied to areas such as hypervelocity impact, shaped-charge penetration, long-rod penetration, small arms, ballistic protection and armor design. Special emphasis is placed on a description of material response at high strain rates. The constitutive and failure behaviors of armor and anti-armor materials, such as hardened steels, ceramics, and tungsten alloys, are described.

Analytical, numerical, and experimental approaches to penetration and perforation problems are addressed. Particular emphasis is placed on analytical modeling of penetration, including a review of many of the models in the literature, and the basic mechanics and assumptions used to develop these models. The applicability and shortcomings of semi-empirical, analytical, and numerical models to various materials and velocity regimes are discussed, and the latest progress in numerical simulation is assessed. Examples of analytical and numerical modeling of projectile impact into armor materials are given. Solution techniques are described and commonalities between seemingly unrelated types of impact problems are presented.

C.2 Objective

ARL’s objective is to provide participants with the necessary background to understand and apply the principles of penetration mechanics to impact potential problems.

C.3 Requirement

The Contractor shall provide a course that involves Government engineers, scientists, and technical managers who are involved in analysis, evaluation, design, research, and development of systems to stop, contain, or enhance the penetration of fragments and penetrators. While there is no formal prerequisite, the course is directed toward personnel with degrees in engineering, the physical sciences, mathematics, or equivalent experience.

The course is tentatively scheduled to take place from 20-24 April 2020.

C.4 Distribution Statement

C.4.1. Determination of the PWS document:

Distribution Statement A: Approved for public release, distribution is unlimited

C.4.2. Determination for Information generated from Contract:

Distribution Statement A: Approved for public release, distribution is unlimited

C.5 Contractor Manpower Reporting

C.5.1 Accounting For Contract Services Requirement – Enterprise-Wide Contractor Manpower Reporting Application (CMRA)

The contractor shall report ALL contractor labor hours (including subcontractor labor hours) required for performance of services provided under this contract for the Army via a secure data collection site. The contractor is required to completely fill in all required data fields using the following web address: http://www.ecmra.mil/.

Reporting inputs will be for the labor executed during the period of performance during each Government fiscal year (FY), which runs October 1 through September 30. While inputs may be reported any time during the FY, all data shall be reported no later than October 31 of each calendar year, beginning with 2013. Contractors may direct questions to the help desk by clicking on “Send an email” which is located under the Help Resources ribbon on the right side of the login page.

C.6 Non-Personal Services

C.6.1 ARL/ALC/Garrison Non-Personal Services

The contractor, as an independent contractor and not as an agent of the Government, shall provide the necessary resources (except those furnished by the Government) to accomplish tasks of the type set forth in the Performance Work Statement.

Contractor employees performing services under this contract shall be controlled, directed and supervised at all times by management personnel of the contractor. The contractor's management shall ensure that employees properly comply with the performance standards outlined in this Performance Work Statement and as required by the contracting officer or the contracting officer's representative (COR). Contractor employees shall perform independent of and without the supervision of any Government official. Actions of contractor employees may not be interpreted or implemented in any manner that results in any contractor employee creating or modifying Federal policy, obligating the appropriated funds of the U.S. Government, overseeing the work of Federal employees, providing direct personal services to any Federal employee or otherwise violating the prohibitions set forth in Parts 7.5 and 37.1 of the Federal Acquisition Regulation (FAR). The Government shall control access to the facility and shall perform the inspection and acceptance of completed work and tasks.
