## Abstract The objective of the present study is to show that the numerical instability characterized by checkerboard patterns can be completely controlled when nonβconforming fourβnode finite elements are employed. Since the convergence of the nonβconforming finite element is independent of the L
We present an alternative formulation for the topology optimization of structures made of incompressible materials, a topic that cannot be tackled using most of the approaches of the current literature that are mainly based on displacement finite elements that are well known to be affected by the lo
