Abstract
This paper discusses development of the boundary element method (BEM) evaluation of a structural weld containing an area of lack of fusion (lof). The lof is treated as a crack; and, consequently will be discussed as if it is indeed a defect in the structural weld. The orientation of the crack can not readily be evaluated with classical methods such as found in Tada [I]. BEM models of "textbook" cases were developed. These results were verified by the classical techniques. BEM was then used to evaluate the real-life situation; and, the results used to recommend corrective action. This application of BEM in design work was chosen to demonstrate the adaptability of BEM to real-life design projects. This type problem will also b
