文摘

We developed a novel approach in modeling crack propagation that requires high order COD terms. We developed finite and boundary elements to this purpose. We implemented and tested the novel finite and boundary elements. We evaluated performances of the new elements. We solved benchmark problems of parameters evaluation and crack growth.
