Abstract
In this study, linear and dynamic analysis of 2-D structures using a new strain based quadrilateral finite element is addressed. The developed element has the three Degrees of Freedom (DOF) at each of the four corner nodes (two general external degrees of freedom and the in-plane rotation). The displacement functions of the developed element satisfy the exact representation of the rigid body modes. Both linear and dynamic analyses are considered. For the dynamic analysis lumped mass and explicit time integration are employed. For the purposes of validation some selected numerical examples are solved using this developed element and the obtained results show its good performance.
