The EPIC (Elastic Plastic Impact Computation) code is a Lagrangian explicit dynamics code for wave propagation, elastic-plastic flow, material failure, fragmentation and complex interfaces. Its initial development began in the early 1970s and development has continued at SwRI since 2007.

Over the next four years, SwRI will improve and update EPIC, aiming to increase its accuracy, expand the types of problems and scenarios it is able to address, and increase its computational efficiency when used on supercomputers and GPU clusters.

His primary role has been co-developer of the EPIC code, which models the dynamic large deformations and failure of solid materials subjected to the extreme loads from high-velocity impacts and explosive detonations, and which is widely used throughout the DoD and the defense industry for the design of weapon systems and armor.

2011年6月1日 · We have worked together at Honeywell, ATK, NCSI (Network Computing Services, Inc.) and SwRI (Southwest Research Institute). In the article to follow I will begin with the early days of the EPIC (Elastic-Plastic Impact Computations) code and then trace some of the developments that occurred over a number of years.

This will include performing computations (using the EPIC code developed at Southwest Research Institute [SwRI]) to evaluate the ability to model ballistic impacts into shaped ceramic structures. The computed results will be compared to ballistic tests performed by JNI Armor to assess accuracy and robustness.

The EPIC-3 work provides a new symmetric arrangement of tetrahedral elements which is more accurate than the traditional non-symmetric arrangement.
