Short and long fiber reinforced thermoplastics material

MAT_002 MAT_022 can reproduce the longitudinal direction but are too stiff in perpendicular direction Orthotropic material models with plasticity Mat_108 can reproduce both direction but since plastics are rate dependent there is a need to take an average strain rate for the material parameters...

Finite Element Analysis of Asphalt Pavement under

Oct 01 2019 0183 32 Athree-dimensional model for the surfacetexture of asphalt pavements is constructed byANSYS LS-DYNA to simulate the boundary conditions of asphalt pavements under impact load in this paper The stress nephograms of the asphalt surface under impact load are calculated and plotted The process of asphalt layer stress development and the variation...

A Fabric Material Model with Stress Map

Historically LS-DYNA 1 has provided a number of options for modeling of fabric all connected to the keyword MAT_FABRIC This material model assumes that the fabric can be modeled as a membrane without bending resistance and provides a collection of features associated with airbag modeling...

Evaluation of Material Models to Predict Material Failure

The material model that is considered is implemented within LS-DYNA and works as a combination of an elasto-plastic model called MAT 024 and a failure model called GISSMO The implementation requires the user to de ne a set of material parameters To obtain these...

Evaluation of Guardrail Posts Installed in Asphalt Mow

Asphalt mow strips are typically used as vegetation barriers around guardrail posts in the design of roadside safety structur Asphalt mow strips have historically been modeled as a rigid layer in simulations this assumption results in significant ground level restraint on the guardrail post However experiments have shown that asphalt rupture should be considered in the analysis of the...
