INFLUENCE FUNCTION METHOD COMPUTER PROGRAM FOR ENGINEERING FRACTURE MECHANICS ANALYSES

A computer program, BIGIF (an acronym for boundary-integral-equation-generated influence functions) has been developed. This program can, through use of influence function (IF) methods, model complicated, multiple transient, three-dimensional, elastic fracture mechanics problems accurately and efficiently, without resorting to expensive numerical stress analysis procedures which necessitate the explicit inclusion of the crack in the idealization of the structure. Application of the influence function (IF) method results in uniformly smaller errors as well as a more than one hundred times lower computer cost when compared to both direct and indirect applications of the finite element (FE) method for three-dimensional crack analyses. Therefore the IF method is recommended for analysis of cracked structures when uncracked stress solutions are available.
