Object-oriented stochastic finite element analysis of fibre metal laminates Original Research Article

This paper deals with issues arising from the stochastic simulation of fibre metal laminates. The elasticity modulus of the composite layer is assumed to be a random process. An object-oriented computational framework is proposed, which can be integrated with an existing object-oriented deterministic infrastructure. This framework is utilized to implement a spectral stochastic version of the solid-like shell element. Modelling aspects particular to the layered nature of the fibre metal laminates are discussed and implemented in the proposed framework. Practical application of the software is illustrated by computations on panels of GLARE (fibre metal laminate).
