摘要：

A family of weight functions for edge and semi-elliptical surface cracks in flat plates and angular corners is presented in the paper. The weight functions were derived using the Bueckner-Rice definition of weight function and the Petroski-Achenbach crack opening displacement expression. A method of deriving the closed form weight functions is presented together with a discussion on the basic assumptions and limitations. The accuracy of all weight functions was examined with respect to available stress intensity factor data. © 1990.
