Abstract
The purpose of the work described in this paper is to study the relation of crack propagation velocity to stress variation arising due to the arrival of a longitudinal unloading wave created during a tensile fracture. The time dependent stress due to the compression wave emanated from the rupture section of the notched round bar specimen of annealed JIS-SS41 steel is observed using the strain gage method. The same problem is theoretically analyzed by postulating three different crack growth models. A crack front of circular shape possessing a radius which increases at a constant rate ( c o k ) with time is assumed, where c o is the propagation velocity of the elastic stress wave and k is the crack velocity factor determined by comparing the experimental results with the theory.
