Yg. Zhang et J. Ballmann, AN EXPLICIT FINITE-DIFFERENCE PROCEDURE FOR CONTACT-IMPACT ANALYSIS OF CRACK EDGES, Archive of applied mechanics, 66(7), 1996, pp. 493-502
A finite difference procedure is proposed to simulate the frictional c
ontact-impact response of crack edges. The procedure takes into accoun
t in an explicit way separation, stick contact and slip contact of the
crack edges. Numerical examples are presented to show the influence o
f the contact-impacting of crack edges on the history of dynamic stres
s intensity factors.
