Adaptive methods for multi‐material ALE hydrodynamics

William J. Rider, Edwin Love, M.K. Wong, O.E. Strack et autres

Abstract Arbitrary Lagrangian–Eulerian (ALE) methods are commonly used for challenging problems in hydrodynamics. Among the most challenging matters are the approximations in the presence of multiple materials. The ALE code ALEGRA has used a constant volume method for computing the impact of …

The SPECTROM-31 Compliant Joint Model: A preliminary description and feasibility study: Nevada Nuclear Waste Storage Investigations project

Duane A. Labreche, Sharon Petney

A deformable continuum joint model, the Compliant Joint Model, has been incorporated into the two-dimensional finite-element computer program SPECTROM-31. The stress-deformation response of a joint set normal to its plane of orientation is elastic and hyperbolic in form. The shear stress-deformation response …
