In this work, transient dynamic stress concentration in a hybrid composite laminate subjected to a sudden internal crack is examined. It is assumed that all fibers lie in one direction and the applied load acts along direction of fibers. Two types arrangements are considered for the fiber; square and hexagonal arrangement. Using shear lag model, equilibrium equations are deduced and upon proper...

Purpose. To develop an approach for determining the stress state of plate structural elements with holes under dynamic loads controlled accuracy. Methodology. The study was carried out on basis Laplace transform and method integral equations. Findings. An to stresses at in plates is proposed, which includes: time coordinate; a numerical transformants displacements based equations; finding origi...
