Finite Element Tools and Simulations Connecting Properties to Performance

National Laboratory: 
Sandia National Laboratories
Computational Tools Class: 
Structure-Properties
Description: 

Fundamental consideration of finite deformation mechanics within the context of nonlinear finite element methodologies integrated with constitutive model domain expertise provides a path to material performance evaluation that is intimately tied to structure-properties relationships.

Capability Bounds: 

Sandia National Laboratories offers continuum-scale models and calculation capabilities.

Unique Aspects: 

The capabilities are distinguished by rigorous application of fundamental physical and mathematical principles, spanning experiments, model development, and regularized numeric, which are progressing toward performance predictions.

Availability: 

Some tools are developed in concert with open-source computational codes produced by SNL (e.g., Albany, now distributed on GitHub). Many tools also are available for use with external collaborators.
