EFFECT OF THE CRACK GEOMETRY AND NOTCH ON STRESS INTENSITY FACTORS IN BONDING OF MATERIALS
Journal Title: Academic Research International - Year 2013, Vol 4, Issue 4
Abstract
The failure of cracked components is governed by the stresses in the vicinity of the crack tip. The singular stress contributions characterized by stress intensity factors. The stress intensity factors depend on the geometryof the component and on loading condition. This paper addresses the evaluation of stress intensity factors (SIFs) of opening, shearing and tearing modes for compact tension specimens for bonding homogeneous materials. The aim of this work is to find the optimal pre-cracked length, crack notch radius and crack notching lei order to eliminate the effect of the menthe SIF and none the Fracture toughness. To achieve this goal ,a three-dimension finite element analysis(FEA) model using ANSYS program is constructed for specimens made of homogeneous materials such as stainless steel bonding with epoxy as a filler material. The effects of notch angle, notch tip radius and pre-crack length on the stress intensity factors are studied for different fracture modes. There salts for the stress intensity factors KI, KII and KIII are obtained using linear elastic fracture mechanics (LEFM) approach.
