Abstract
It is known that the standard full integration ten node tetrahedral element is inaccurate for thin nearly incompressible structures. The objective of this work is to develop a ten node tetrahedral Cosserat Point Element (CPE) for nonlinear isotropic hyperelastic materials. Hyperelastic constitutive equations for the CPE are developed by treating the element as a structure with a strain energy function that is restricted to satisfy a nonlinear form of the patch test. A number of examples are considered which demonstrate that the resulting CPE is accurate and robust.
