Strength and damage modeling in FLAG (U) [Slides]
- Los Alamos National Laboratory (LANL), Los Alamos, NM (United States)
Recent improvements to the FLAG code have included a modification of the Preston-Tonks-Wallace (PTW) strength model and a re-factoring the Tensile Elastic-Plastic (TEPla) damage model. The PTW strength model has been modified to enhance modeling through transitions from low strain-rate (thermal activation) regime to the high strain rate (over-driven shock) regime. The presentation discusses the implementation of the modified strength model and some of the computational issues.
