Outline
• Nature of the problem • Workflows and Infrastructure • Linear CAE material libraries • Non-linear CAE material libraries • ANSA connectivity
strengthening the materials core of manufacturing enterprises
Nature of the problem
• Wide variety of simulations: NVH, crash, fatigue, process…. • Need self-consistent data, eg. same modulus, Poisson’s, yield…
• Unmanaged material file repositories • Not easy to add/edit/replace material files
• Material naming conventions • Inconsistent material nomenclature in CAD v. CAE • Material name or specifications in material callouts
• Unit systems • Traceability of CAE material files to material data source • Integration between CAD and CAE for materials

Conclusions
• Process for handling materials consistently in CAD and CAE • Materials, specifications, properties, material cards are stored in
a single master database • Database deploys outputs for both CAD and CAE • Material callouts are same for both CAD and CAE • Material Specification based callouts can be used • Consistent and traceable data for the enterprise from a single
managed source
