Analysis of Moment and Torsion in Skew Plates Using ABAQUS

The increased utilization of skew plates in thin-walled structural components of aircrafts, submarines, automobiles, and other high-performance application areas have necessitated a strong need to understand their characteristics. This paper presents the bending analysis of isotropic skewed plates using the finite element software ABAQUS Simulia. Modeling was done in ABAQUS Simulia using the SC8R element as it gave better results for shell structures. An analysis is done on skew plates of various skew angles and aspect ratios with all end clamps subjected to uniform pressure and the results are generated. The effect of skew angle, aspect ratio, and thickness of the plate on various parameters like bending and torsional moments, support shear, and deflection are separately presented which may serve as a benchmark for further research. From the results, it is observed that the maximum central deflection decreases with an increase in skew angle. The negative reaction was found to develop at the acute angle corners and it increased as the skew angle increased. Bending moments were found to decrease and torsion was found to increase with an increase in skew angle.
