A Novel Quadrilateral Element for Dynamic Response of Plate ‎Structures Subjected to Blast Loading

Abstract

We study the dynamic response of plate structures subjected to blast loading. This load is introduced in dynamically excited form over time. Two assumptions are given to ensure the physical properties of dynamic problems. The plate structures are studied its response under explosion. The governing equation with respect to the motion is solved by using a novel quadrilateral element SQ4T related to the twice interpolation strategy (TIS) and the average acceleration method of Newmark’s family. Our solutions are compared with reference solutions to confirm the accuracy of the proposed element.
