Cálculo de factores de intensidad de tensión estáticos y dinámicos mediante el metodo de los elementos de contorno con formulación hipersingular

Abstract

The Mixed Boundary Element Method, a combination of the equations corresponding to the integral representations of displacements and tractions: is used to propose and evaluate a riew methodology for computing dynamic Stress Intensity Factors in the frequency doniain. The paper starts presenting the hypersingular fundamental solution, extracting their singular parts, and constructing a new discontinuous Singular Quarter Point element. Finally, various parametric eornputations and applications are described to illustrate the simplicity and accuracy of the proposed method as applied to both static and dynamic problems.
