Development of a Blast Event Simulation Process for Multi-Scale Modeling of Composite Armor for Light Weight Vehicles (PREPRINT)
Abstract
This paper presents the development of a multi-scale simulation process for modeling the response of a vehicle with composite armor to the blast loads from an explosive threat. The new process can be used for improving the blast resistant capabilities of the composite armor by configuring its properties at the micro-level. A Blast Event Simulation system (BEST) that facilitates the easy use of LS-DYNA or ABAQUS for conducting a complete sequence of explosive simulations and the inclusion of Anthropometric Test Device (ATD) comprises one of the two main foundation components of the new development. The Micromechanics Analysis Code (MAC) developed by NASA Glenn comprises the second main foundation component. Details from a validation study of BEST associated with the response of a generic structure and an ATD placed inside it to an explosion are discussed. The development of the new multi-scale simulation capability is discussed and a case study is presented. The case study demonstrates how the new simulation approach can determine a matrix-fiber configuration and the orientation of the laminates at the micro-level for designing blast resistant composite armor that offers similar levels of protection with steel but at significantly reduced weight.
