"Reliable prediction of the behavior of structures made from polymers is a topic under considerable investigation in
engineering practice. Especially, if the structure is subjected to dynamic loading, constitutive models considering
the mechanical behavior properly are still not available in commercial finite element codes yet. In our paper, we
present a new constitutive law for polymers which recovers important phenomena like necking, crazing, strain rate
dependency, unloading behavior and damage. In particular, different yield surfaces in compression and tension and
strain rate dependent failure, the latter with damage induced erosion, is taken into account. All relevant parameters
are given directly in the input as load curves, i.e. time consuming parameter identification is not necessary. Moreover,
the models by von Mises and Drucker-Prager are included in the description as special cases.
With the present formulation, standard verification test can be simulated successfully: tensile and compression test,
shear test and three point bending tests."

LS-DYNA contains a wealth of material models that allow for the simulation of transient phenomena. These models are often quite complex and difficult to calibrate. We present CAE Modeler, a generalized pre-processor software used to convert material property data into material parameters for different material models used in CAE. In this paper, CAE Modeler is used to streamline the conversion of rate dependent stress-strain data into material parameters for the MAT_024 material model. The interactive software is capable of handling all three rate dependency options of MAT_024 and outputs a data file that can be read directly into LS-DYNA. Support for other material models is envisaged.

Material Wizard provides two options to create a new material file,
Custom: If you have property data of a new material, you can select Custom to add the property data into Material Wizard.
From Exterior Sources: If you find a new material in other sources, you can convert other format of the material file into Moldex3D format of the material file.

Matereality

Virtual product development today has become a complex process involving CAD, FEA, CAE,
and physical testing. Material properties form the glue that link the simulation and real life
behavior together. Most often, the properties of the materials used in different stages of the
product life cycle vary depending on the application. Hence, the engineers and technicians within
the enterprise need to have access to not just the simple single point properties that help
determine the suitability of a material, but also the more detailed behavioral property data that
affect design, simulation and failure analyses. A common platform for the storage and effective
deployment of these properties system wide is critical to the efficiency, cost, and quality control
through PLM. We present a technology, Matereality that accommodates diverse properties of all
the different materials used by an enterprise, its suppliers and collaborators. The cost benefits are
immediate, besides improved interoperability and consistency in material data use through the
enterprise.
