On non-stationary response of cracked thin rectangular plates acted upon by a moving random force

This paper is aimed to examine the dynamics of cracked thin rectangular plates subjected a moving non-stationary random load. A load considered with constant mean value, velocity along plate, and five different covariance patterns,the white noise, constant, exponential, cosine wave, exponential covariance. Accordingly, an intact plate’s orthogonal polynomials in combination well-known corner functions are employed explore mechanical behavior plate. As non-dimensional deflection values, squared values obtained for damped undamped at points. An inclusive parametric study performed effects inclined crack angles lengths on middle point plates. Based results, it concluded that there nonlinear relations between increasing incline as well values. Furthermore, found cases, profounder than other four patterned cases.
