✦ Synopsis

In this paper, an elastoplastic analysis based on fuzzy mathematics and using finite element method will be described. The Drucker-Prager yield criterion and the elasto-plastic matrix are fuzzified for the non-linear analyses which adopt the initial stress method for the solution. A numerical example is given to illustrate the possible variations in the displacements and the extent of plastic zones at the discrete membership functions. A reliability index of a membership grade based on the concept of non-probabilistic entropy is also proposed.

## Abstract Advances in technology and interest in limit state design have made the inclusion of non‐linear effects, such as elasto‐plastic behaviour, desirable in the analysis of many structures. Improvements in solution algorithms coupled with parallel developments in high speed digital computers
