Ph. Wen et al., THE INFLUENCE OF ELASTIC WAVER ON DYNAMIC STRESS INTENSITY FACTORS (2-DIMENSIONAL PROBLEMS), Archive of applied mechanics, 66(5), 1996, pp. 326-335
In this paper, an indirect boundary integral equation method for the s
olution of dynamic crack problems is presented. The Laplace transform
method is used to derive the fundamental solutions for the opening mod
e (mode I) and the sliding mode (mode II) displacement discontinuity.
Accurate dynamic stress intensity factors K-N(t) (N = I,II) resulting
from different time-dependent loads on the crack surface are obtained.
The specific influences of the various elastic waves on the stress in
tensity factors can be clearly seen from the results.
