An efficient ABAQUS solid shell element implementation for low velocity impact analysis of FGM plates

Résumé

The main objective of this paper is to develop a numerical model susceptible to solve the numerical locking problems that may appear when applying the conventional solid and shell finite elements of ABAQUS. This model is based on an hexahedral solid shell element. The formulation of this element relay on the combination of the Enhanced Assumed Strain (EAS) and Assumed Natural Strain (ANS) methods with modified FSDT. The developed element is implemented into the ABAQUS user element (UEL) interface. The performance of this element is demonstrated by different benchmark tests from literature. Our contribution consists on applying a single solid shell element through the thickness direction to predict the low velocity impact behavior on FGM circular plates.
