On numerical implementation of a coupled rate dependent damage‐plasticity constitutive model for concrete in application to high‐rate dynamics
Abstract
Purpose
To provide an efficient and robust constitutive equations for concrete ion application to high rate dynamics.
Design/methodology/approach
Develops an explicit‐implicit integration scheme for a concrete model. This robust integration scheme ensures computational efficiency. Comparison between simulations of impact of equivalent aircraft engine projectiles and the tests carried out in Sandia laboratory also demonstrate its efficiency.
Findings
Shows that modeling transient high rate dynamic behavior of concrete is very important to take into account for design concrete structures in the cases of dynamic loading conditions, such as an impact on the structure.
Originality/value
Proposes an original integration scheme for a coupled rate dependent damage plasticity model. Also provides a detailed consideration of the numerical stability of this kind of scheme for rate‐dependent damage model.
