Abstract A 4‐node element with 1 integration point is developed for the analysis of elastoplastic large strains. It is based on the Hu‐Washizu principle and uses a co‐rotational formulation. Special care is taken to avoid spurious zero‐energy modes and incompressibility locking. This element successfully passes the large strain patch test. It proves to be accurate and computationally very cheap.
