Abstract

A locking‐free unsymmetric 8‐node solid‐shell element with high distortion tolerance is proposed for general shell analysis, which is equipped with translational degrees of freedom only. The prototype of this new model is a recent solid element US‐ATFH8 developed by combining the unsymmetric finite...
