Abstract

In the last one and a half decades, a considerable amount of three‐dimensional continuum finite element models have been proposed for plate/shell analysis. These continuum elements possess no rotational degree of freedom and are sometimes known as solid‐shell elements. Development of solid‐shell elements is not straightforward. To be applicable to thin‐ and curved‐shell analysis, element deficiencies known as shear, membrane, trapezoidal and thickness lockings must be envisioned. To alleviate or resolve them, advanced finite element techniques, including reduced integration, stabilization, assumed natural strain, enhanced assumed strain, hybrid strain and hybrid stress methods, have been resorted to. This article aims to provide a review of past efforts at formulating reliable solid‐shell elements.
