Abstract
In a separate power, the authors presented a total Lagrangean rate formulation for a hybrid stress finite-element method, based on a rate complementary energy principle which involves both the rates of Piola-Lagrange stress and rotation as variables, for finite strain anaysis of nonlinear elastic compressible solids. In this paper, the method is extended to the case of precisely incompressible rubber-like materials. Two plane stress problems, one corresponding to a biaxial strip test and, the other, sheet with a circular hole, both involving strains in excess of 100 percent, are solved and the numerical results are discussed.
