Nonlinear response of a beam under stationary random excitation by improved stochastic linearization method
A new stochastic linearization technique is employed to investigate the nonlinear mean square response of a beam with arbitrary boundary conditions under time-dependent stationary random excitation. To demonstrate the accuracy of this new method, mean square response is obtained through both the new and conventional versions of the stochastic linearization technique. An example of a beam with both ends simply supported is presented for the case of white noise excitation to illustrate the present method.
