Abstract
This paper presents the application of the finite element reliability metho d to the evaluation of the statistical properties of localisation phenomena . Material and boundary constraint imperfections are considered. The latter are imposed through Lagrange multipliers. The evaluation of the sensitivit y to the stochastic basic variables, which is needed in the reliability met hod, is outlined. Numerical simulations of mode-I and mode-II localisation phenomena are presented. (C) 2000 Elsevier Science Ltd. All rights reserved .
