Abstract: A three-dimensional surface integral and finite element hybrid method has been developed for modeling arbitrarily shaped surface cracks in complex structural components. Accurate stress intensity ...

Abstract: The surface integral method, an indirect boundary element method that represents a crack as a distribution of force dipoles, has been developed to model three-dimensional nonplanar crack growth ...

Abstract: A technology for non-intrusive real-time structural health monitoring using piezoelectric active sensors is presented. The approach is based on monitoring variations of the coupled electromechanical ...
