DYNA2D:An Explicit Finite Element and Finite Difference Code for Axisymmetric and Plane Strain Calculations (User's Guide).

摘要

DYNA2D is an explicit two-dimensional plane strain and axisymmetric Lagrangian finite element and finite difference code. Spatial discretization may be accomplished by constant-stress elements that can be degenerated to triangular zones,constant-pressure variable-node elements,nine-node Lagrange elements,or finite difference zones based on the HEMP difference equations. A general slide-line capability is implemented that admits frictional sliding along arbitrary,intersecting frid lines. Gravity effects are accounted for in the initialization whenever needed,as in soil--structure interaction problems. Loading functions admit pressure and shear loadings along a boundary,body force loadings due to spinning and base accelerations,and nodal velocity--time histories. (ERA citation 03:049033)
