Abstract

This paper concerns the applications of the stochastic boundary element method (SBEM) to probabilistic problems of shape sensitivity analysis and identification. Numerical examples for 2-D and 3-D problems are presented. 1. Introduction One knows that boundaries bounding real bodies are very complicated as far as their geometrical shape is concerned. Usually they are uneven and the irregularities do not easily lead to a unique deterministic description. Therefore boundaries of such bodies can be defined stochastically. SBEM (cf. Burczynski [3]) is a very useful and natural technique for modelling such
