Calculation of the Electrical Resistance of a Compact Tension Specimen for Crack-Propagation Measurements
The electrical resistance of a notched compact specimen for determination of plane-strain fracture toughness was calculated using numerical methods coupled with the Schwarz-Christoffel transformation. Experimental measurement of this resistance is commonly used to obtain the crack length in notched specimens subjected to stress corrosion and hydrogen embrit t lement tests. The results presented...
متن کاملA boundary element analysis of crack-propagation mechanism of micro-cracks in rock-like specimens under a uniform normal tension
In this work, the mechanism for fracture of brittle substances such as rocks under a uniform normal tension is considered. The oriented straight micro-cracks are mostly created in all the polycrystalline materials resulting from the stress concentrations. The present work focuses on the interactions of the pre-existing micro-cracks, which can grow and propagate within a rock-like specimen. The ...
متن کاملFinite Element Computational Approach of Fracture Toughness in Composite Compact - Tension Specimen
For composite structure, fracture toughness is a dominant parameter when using cohesive laws to predict the nominal strength. In the present study the compact tension test is performed on composites structures and is simulated using FEM. The process of fracture takes places in two sequential stages, crack initiation and crack propagation. The critical energy release rate is determined using the...

متن کاملCrack propagation as a free boundary problem.
A sharp interface model of crack propagation as a phase transition process is discussed. We develop a multipole expansion technique to solve this free boundary problem numerically. We obtain steady state solutions with a self-consistently selected propagation velocity and shape of the crack, provided that elastodynamic effects are taken into account. Also, we find a saturation of the steady sta...
