Stress Concentration Induced by Synnergisticaly Interacting Geometric Discontinuites

Abstract

Stress concentrations induced by geometric discontinuities can have detrimental effects on the structural reliability and integrity of components subjected to static or cyclic loadings. Thus, it is instrumental to have the knowledge to predict the stress concentration levels induced by a wide range of geometric discontinuities that cannot be avoided in engineering applications. This work aims to shed light into the cooperative interactive stress concentrating effects of coexisting geometric discontinuities. In particular, this work computationally investigates the stress concentration induced by the interaction of closely placed through-holes and fillets. Results show that the stress concentration induced by the cooperative interaction of the investigated geometric discontinuities far exceeds the stress concentration induced independently by each of them.
