NIKE2D is a fully vectorized, implicit, finite-deformation, large strain, finite element code for analyzing the response of two-dimensional axisymmetric, plane strain, and plane stress solids. A variety of loading conditions can be handled including traction boundary conditions, displacement boundary conditions, concentrated nodal point loads, body force loads due to base accelerations, and body force loads due to spinning. Slidelines with interface friction are available. Elastic, orthotropic-elastic, elastic-plastic, thermo-elastic-plastic, soil and crushable foam, linear viscoelastic, thermo-orthotropic elastic, elastic-creep, and strain rate dependent material models are implemented. Nearly incompressible behavior that arises in plasticity problems and elasticity problems with Poisson's ratio approaching 0.5 is accounted for in the element formulation to preclude mesh lock-ups and associated anomalous stress states. Four node isoparametric elements are used for the spatial discretization, and profile (bandwidth) minimization is optional.
