Description

A three-dimensional constitutive model has been developed for modeling orthotropic composites subject to impact loads. It has three distinct components - a deformation model involving elastic and plastic deformations; a damage model; and a failure model. The model is driven

A three-dimensional constitutive model has been developed for modeling orthotropic composites subject to impact loads. It has three distinct components - a deformation model involving elastic and plastic deformations; a damage model; and a failure model. The model is driven by tabular data that is generated either using laboratory tests or via virtual testing. A unidirectional composite - T800/F3900, commonly used in the aerospace industry, is used in the verification and validation tests. While the failure model is under development, these tests indicate that the implementation of the deformation and damage models in a commercial finite element program, LS-DYNA, is efficient, robust and accurate.
