Abstract
This paper introduces a Nonlinear Finite Element Analysis on damage propagation behavior of composite panels under in-plane uniaxial quasi-static compression after a low-velocity impact. The major damage modes due to the impact were incorporated into the model. A consequential core crushing mechanism was incorporated into the analysis. The critical far field stress corresponding to the onset of damage propagation near the damage zone was captured successfully with a good correlation with experimental data. These values can be used to predict the residual compressive strength of low-velocity impacted composite sandwich panels.
