Tahoe

Abstract

Tahoe is a research-oriented platform for the development of numerical methods and material models. The goal of the work surrounding Tahoe is the simulation of stresses and deformations for situations that cannot be treated by standard continuum simulation techniques. These situations include material fracture or failure, interfacial adhesion and debonding, shear banding, length-scale dependent elasticity and plasticity, and deformation in small-scale structures. Aside from a collection of standard finite elements, Tahoe includes meshfree simulation capability and particle methods. Tahoe includes a number of "cohesive" approaches for modeling fracture. These include both surface and bulk constitutive models that incorporate cohesive behavior. Tahoe is capable of performing static and transient dynamic coupled-physics analysis in two and three dimensions. Many capabilities support parallel execution.
