New Generation Modeler for LS-DYNA Material Parameter Conversion
We describe a new software component that takes into consideration the unique multi-variate nature of LS-DYNA material models. Rate-dependent models require adjustment and tuning of many material parameters to fit the rate-dependent tensile properties. Drawing upon a robust back-end data model, a graphical user interface provides drag and drop capability to allow the user to perform tasks such as model extrapolation beyond tested data, modulus change, rate dependency tuning and failure criteria adjustment while assuring self-consistency of the underlying material model. Unit system conversions are also facilitated, eliminating error and ensuring that material inputs to simulation correctly reflect the intent of the CAE analyst. The utility of the Matereality CAE modelers is illustrated with examples for LS-DYNA material models MAT_019, MAT_024 and MAT_089 LCSR.

Software for Materials
Materials information is an aspect of product data that must be accessible by engineering teams at many phases of the product lifecycle. Every aspect of this complex and highly varied data can now be carefully organized in libraries and supported by analytical tools and software modules to aid materials engineers, CAE engineers, test labs and designers in their daily tasks. When deployed across the enterprise, the Matereality software brings harmony, efficiency and control while minimizing risk.
Software solutions for everyone
Matereality provides material database creation software, productivity enhancing software, and customized application management solutions for groups and individuals involved in manufacturing enterprises.
Designed by engineers, for engineers
Our goal is to aid in all of the steps of product lifecycle management, enhancing productivity, and eliminating potential risks from inappropriate use of material data.
