✦ Synopsis

A triangular finite element was developed for the purpose of computing time dependent stress intensity factors in cracked panels caused by dynamic loadings. An explicit consistent mass matrix was formulated for use with an existing stiffness matrix developed earlier. The singular finite element and a conventional triangular plane element were used to solve a plane problem with a known solution to evaluate the accuracy. Several other problems with time dependent loadings were solved and discussed.
