In some of our applications we are interested in how a structure behaves after it buckles. When a structure collapses completely, a single surface may buckle enough that it comes into contact with itself. The traditional approach of defining master a

The state of Lagrangian hydrocodes for computing the large deformation dynamic response of inelastic continua is reviewed in the context of engineering computation at the Lawrence Livermore National Laboratory, U.S.A., and the DYNA2D/DYNA3D finite el

The major costs of large implicit finite element calculations, particularly in three dimensions, arise from computing solutions to systems of linear equations. Direct methods, i.e., those based upon Gaussian elimination, can easily require prohibitiv

The analysis of low velocity impacts is necessary for designing everything from safe automobiles to safe shipping casks for nuclear material. Although great strides have been made in reducing the cost of impact analysis, the cost must be reduced even

The two- and three-dimensional contact algorithms used in the finite element programs developed at the Lawrence Livermore National Laboratory are described in this paper. We are interested in both static contact and dynamic impact problems and, conse

DYNA3D is an explicit three-dimensional finite element code for analyzing the large deformation dynamic response of solids. Elastic-plastic and hyperelastic material behavior can be modeled. A contact-impact algorithm permits gaps and sliding along m

We model the dynamic response of two ytterbiumm gauges using the two‐dimensional Lagrangian finite difference code DYNA2D. The gauges are embedded in a PMMA medium. The stress and strain state of each element of the gauge is then used to calculate
