An improved computational framework based on the dual boundary element method for three-dimensional mixed-mode crack propagation analyses

This study presents an improved computational framework based on the Dual Boundary Element Method (DBEM) for modelling three-dimensional mixed-mode fatigue crack propagation in geometrically complex structural components. The improvements are: (i) an input data scheme based on an alternative collocation strategy, which enables the discretization of each Non-Uniform Rational B-splines (NURBS) surfaces of geometrical models without any concerning...
