✦ Synopsis

AImtract-A procedure is described that allows one to determine averaged weight functions by a direct adjustment to reference stress intensity factor solutions. In contrast to well known methods hased on a nearly complete COD description, the proposed evaluation only requires the local stress intensity factors of reference loading cases to he known. A two-term weight function hased on constant stress as the reference loading case and on the continuity of the weight function is compared with a three-term solution hased on the hending load case as an additional reference solution.
