Abstract

Using the fiber bundle cells (FBCs)-based stochastic material model developed in the first part of this paper, we derived a stochastic version of the classical composite laminate theory (SCLT) for controlled multiaxial deformation, where the strength parameters are stochastic variables. This model (SCLT) enables to describe both the deformation and the damage processes in each lamina up to the ultimate failure. By discussing some examples of simpler tensile load, we demonstrate the applicability of the results.
