Developing design methodologies based on experimentally validated predictive numerical simulation methods will enhance existing capabilities in predicting failure modes and structural design optimization for the high velocity impact problems. This paper is thus concerned with the setup of a methodology for modeling and simulation of the containment problem for the case of a real hybrid metallic/soft layered composite fancase structure. To realize this new design, a debris protection fan case composed of a basic metallic shell structure with a dry Kevlar wrap around it is considered. The fan blade is made of titanium alloy modeled by a Johnson-Cook elastoplastic material in ABAQUS, while the metallic structure of the fan case is made of aluminum alloy also modeled as an elastoplastic material. A multilayered Kevlar woven dry fabric structure is wrapped around the thin aluminum shell to form a soft hybrid fan case. A woven fabric material model developed in ABAQUS has been used. This material model can capture the ballistic response of multi-layer fabric panels and is implemented as a VUMAT subroutine in an equivalent smeared shell element corresponding to the representative volume element (RVE) for computational efficiency. The aim is to assess how this material model can be applied in a real industrial application.
