Abstract
The report analyzes commercially available finite eleent codes for suitability in studying thermal attack of energetic material. Two specific scenarios, cook-off and hot fragment attack are used to define the needs and analyze the suitability of the codes. The nonlinearities and range of time scales involved make the problem difficult. Suitable programs provide special elements, materials and/or loading to accomplish the modelling. These may be provided either by built-in capability or by allowing the analyst to program Fortran subroutines. Other criteria for code selection include: (1) the computational methods used (implicit or explicit; (2) the ease of setup of a problem and anlaysis of the results (pre- and post-processors); (3) the computational resources needed; and (4) the availability of support from a code's developpers. Recommendations are made for a code appropriate to DREV's needs.
