Article Synopsis
- The study proposes a new method for calculating the transient probability density function (PDF) for nonlinear oscillators influenced by random stimulation, extending previous techniques with an evolutionary exponential-polynomial approach.
- By using weighted residual errors and developing ordinary differential equations, the research allows for the numerical determination of undetermined variables to better model system responses.
- The findings show that this improved method is more effective and efficient than traditional Monte Carlo simulations, particularly capturing asymmetrical PDF solutions and examining the effects of nonlinearity and modulated Gaussian noise on system behavior.
In this paper, a weight function method based on the first four terms of a Taylor's series expansion is proposed to determine the stress intensity factors of functionally graded plates with semi-elliptical surface cracks. Cracked surfaces that are subjected to constant, linear, parabolic and cubic stress fields are considered. The weight functions for the surface, deepest and general points on the crack faces of long and deep cracked functionally graded plates are derived, which has never been done before in the literature.
