A general formulation of an assumed strain method in the context of mixed finite elements is presented. Attention is focused on finite deformation problems in solid mechanics. Specifically, the paper investigates the proposed formulation in the setting of incompressible hyperelasticity. Representative simulations illustrate the performance of the formulation.
