Abstract
A study conducted to select computer codes for modelling self-forging fragment formation and target impact is reported. The basic features of such codes are reviewed, and the application of numerical modelling techniques to self-forging fragment design is discussed. Eleven codes are included in the study, all of which are found to be adequate with respect to modelling equations of state, stress-strain and failure. In evaluating the codes, emphasis is placed on such features as documentation, three-dimensional capability and modelling of severe distortions. Based on these criteria, the EPIC-2 and EPIC-3 codes are selected as the codes which best fulfill the DRES numerical modelling requirements for self-forging fragment research.
