Abstract
A multiple-quadrature underintegrated hexahedral finite element, which is free of volumetric and shear locking, and has no spurious singular modes, is described and implemented for nonlinear analysis. Finite el ement formulations are derived in the corotational coordinate system. The use of consistent tangent operators for large deformation elastopl asticity with nonlinear isotropic/kinematic hardening rules preserves the quadratic rate of convergence of the Newton's iteration method in static analysis. Test problems studied demonstrate the efficiency and effectiveness of this element in solving a wide variety of problems, i ncluding sheet metal forming processes.
