Inter-element stabilization for linear large-deformation elements to solve coupled CFD/CSD blast and impact problems

摘要

In this work a stabilized large deformation element suitable for real coupled fluid/solid simulations is presented.The element uses a mixed interpolation (Q1/P0):Standard continuous tri-linear finite element (FE) functions for the kinematic variables displacements,velocities and accelerations),and a constant pressure per element (piecewise discontinuous pressures).
