Abstract
A new strain rate dependent material and failure model referred to as the M2C Model was generated suitable for modeling the static and dynamic material behavior of fiber reinforced composites. The M2C consists of an orthotropic viscoelastic constitutive model in combination with an enhancement of the Failure Mode Concept (FMC) of Cuntze for dynamic loading conditions and was implemented into the finite element Code LS-DYNA3D as user defined material model. A [0°|90°] glass fiber reinforced composite was investigated under different types of loading and loading directions within seven orders of magnitude of strain rate. The finite element results are compared with experimental results. In the principal loading directions and under arbitrary loading conditions an impressing agreement was achieved.
