Abstract
A method has been proposed to compute the probability that a mode I dynamic crack in an isotropic, homogeneous, two dimensional structure remains within a safe domain during a given interval of time. The method accounts for randomness in time varying applied loading, dynamic fracture toughness and initial crack length. It models the load and dynamic fracture toughness as random processes. The method is based upon the theories of linear elastic dynamic fracture mechanics, theories of random vibrations and First and Second order reliability methods. An example of an infinite plate structure with a dynamic mode I crack has been demonstrated to show the use of the method.
