Surface contact of elliptical crack under normally incident tension-compression wave

摘要

Surface contact interaction of a plane elliptical crack under normally incident tension-compression wave is solved by the method of boundary integral equations. The contact forces and the displacement discontinuity of the crack edges are examined. The dependence of the mode I stress intensity factor on the wave number is studied. The solution is compared with the results obtained for an elliptical crack without allowance for crack edges contact interaction. (C) 2003 Published by Elsevier Ltd. [References: 15]
