M. Kaminski et M. Kleiber, Perturbation based stochastic finite element method for homogenization of two-phase elastic composites, COMPUT STRU, 78(6), 2000, pp. 811-826
The main idea of the paper is to apply the second order perturbation and st
ochastic second central moment technique to solve the homogenization proble
m. In order to determine the effective elasticity tensor, the prevailing co
mputational methodology discussed in the literature so far was the Monte-Ca
rlo simulation providing appropriate expected values and higher order proba
bilistic moments of the effective tensor components. The technique applied
in this paper aims at significantly reducing the computational cost of the
simulation without sacrificing the solution accuracy. The numerical example
substantiates this claim in the case of a periodic fiber-reinforced plane
strain composite with random fiber and matrix Young's moduli. (C) 2000 Publ
