Jb. Ferrer et al., THE INFLUENCE OF CRACK ACCELERATION ON THE DYNAMIC STRESS INTENSITY FACTOR DURING RAPID CRACK-PROPAGATION, International journal of fracture, 87(3), 1997, pp. 77-82
A finite element model is used to compute the dynamic stress intensity
factor (S.I.F.) during rapid crack propagation. It is shown that the
inertial effects in a transient dynamic linear elastic analysis for an
accelerating and decelerating crack can be responsible for the non un
iqueness of the S.I.F, at a given crack speed.
