Stochastic Finite Elements in Reliability-Based Structural Optimization

Application of stochastic finite elements in structural optimization is considered. It is shown how stochastic fields modelling e.g. the modulus of elasticity can be discretized in stochastic variables and how a sensitivity analysis of the reliability of a structural system with respect to optimization variables can be performed. A computer implementation is described and an illustrative example is given.Application of stochastic finite elements in structural optimization is considered.
