This report is an updated user manual to the 1991 version of NIKE2D, and serves as a temporary theoretical manual. NIKE2D is an implicit finite element code for analyzing the finite deformation, static and dynamic response of two-dimensional, axisymmetric, plane strain, and plane stress solids. The code is fully vectorized and available on several computer platforms. A number of material models are incorporated to simulate a wide range of material behavior including elastoplasticity, anisotropy, creep, thermal effects, and rate dependence. Slideline algorithms model gaps and sliding along material interfaces, including interface friction and single surface contact. Interactive graphics and rezoning is included for analyses with large mesh distortions. In addition to quasinewton and arc-length procedures, adaptive algorithms can be defined to solve the implicit equations using the solution language ISLAND. Each of these capabilities and more make NIKE2D a robust analysis tool.
