DESCRIPTIONNIKE3D is a large deformations 3D finite element code used to obtain the resulting displacements and stresses from multi-body static and dynamic structural thermo-mechanics problems with sliding interfaces. Many nonlinear and temperature dependent constitutive models are available.

MEDIA QUANTITY1 
METHOD OF SOLUTIONNIKE3D uses Newton and Quasi Newton Raphson iterations within an implicit loop to solve the non-linear systems of equations. Its element library consists of 8 node hexahedrals, a number of 4 node shell, 2 node beam, discrete type and contact elements for its finite element discretization. It also performs dynamic analysis using Newmark''s method for integration of the nodal accelerations and velocities, and eigenvalue analysis using subspace iteration based on the linear stiffness matrix. Temperature states for thermal analysis can be read from TOPAZ3D plots.
