STATIC AND DYNAMIC ANALYSIS OF CENTER CRACKED FINITE PLATE SUBJECTED TO UNIFORM TENSILE STRESS USING FINITE ELEMENT METHOD

The study of crack behavior in a plate is a considerable importance in the design to avoid the failure. This paper deals with investigation of stress intensity factor, Von-Misesstress ( ? Von-mises ), natural frequency, mode shape and the effect of excitation frequency on the finite center cracked plate subjected to uniform tensile loading depends on the assumptions of Linear Elastic Fracture Mechanics (LEFM) and plane strain problem. The stress intensity factors mode I (K I ) are numerically calculated by finite element solution using ANSYS (ver. 15) software and theoretically using standard equations for different crack length s and plate dimensions.
