Pre-processor Software for Calibration of LS-DYNA® Material Models

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. full post

Create a New Material File in Moldex3D R15

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. full post

Enterprise-Wide Materials Data Management Ensures CAE Fidelity

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. full post
