Abstract

Realistic prediction of dynamic responses in electrorheological (ER) media demands spatially stochastic constitutive modeling. Sample random fields for yield stress functionals can be constructed for numerical simulation with finite and boundary elements on the basis of the covariance relations obtained from experimental data. This paper focuses on a computational strategy to implement such observed responses. The present formulation of the stochastic constitutive relation has been extended for two and three dimensional problems by employing the standard techniques of the invariant formulation generic to mathematical theory of continuum mechanics. Symbolic computer programs are emphasized along with numerical codes for critical evaluation of the proposed finite/boundary element schemes.
