Abstract: This paper investigates the application of importance sampling method to estimating the first passage probability of single-degree-of-freedom elastoplastic systems subjected to white noise excitations. The importance ...

Abstract: A method for constructing an approximation of the critical excitation that drives an elastoplastic system from rest to a target threshold at a specified time instant, referred to as the “suboptimal excitation,” is presented ...

Abstract: The problem of crack detection has been studied by many researchers, and many methods of approaching the problem have been developed. To quantify the crack extent, most methods follow the model updating approach. This ...

Abstract: This paper presents a study of Lamb wave scattering and mode conversion at a delamination in quasi-isotropic (QI) composite laminates. The study employs the fundamental antisymmetric mode (A0) Lamb wave as the incident ...
