Simulation and Finite Element Analysis for Subsurface Damage in Glass under ball impact in Abaqus

An understanding of the response of brittle and ductile materials under hyper velocity impact is  required for analysis of the space debris and micro meteoroid impact flux via retrieved spacecraft  surfaces. Brittle material surfaces exposed in Low Earth Orbit include solar arrays and windows.  Laboratory experiments are able to access only a small fraction of the impactor parameters  encountered in space (velocity, diameter, density, shape, composition and impact angle).In this simulation ball is modeled as three dimensional shell part and glass as solid part with half mm thickness. To model ball behavior hyper elastic material has been used and to define the glass behavior under high pressure load with high strain rate it should be necessary to use a proper material model .You can see a figure of the assemble parts with a real case at below

The impact phenomenon is a dynamic process originally so dynamic explicit is appropriate for it. Surface to surface contact with friction behavior is used to model the contact. In this tutorial to model gas behavior FLUID CAVITY technique has been used with molar heat capacity and molecular weight for gas inside the ball.The glass needs small mesh size to have a proper response under the impact so in need to be used smaller element size in the impact zone. During the impact the failure of glass is obvious and like that the ball experienced a large deflection. You can some figures of the results at below
