The sensitivity of conventional finite element formulations to distorted meshes is a well-known problem. In this work, it is investigated whether an 8-node Petrov-Galerkin f inite element formulation can reduce this mesh-sensitive behavior when simulating linear-elastic axisymmetric problems. The numerical investigations show that the Petrov-Galerkin formulation exhibits significantly better behavior than the Bubnov-Galerkin formulation in certain cases. However, the results also indicate that this is not generally the case.
