Jp. Zhao et al., THE APPLICATION OF 2D ELASTIC STOCHASTIC FINITE-ELEMENT METHOD IN THEFIELD OF FRACTURE-MECHANICS, International journal of pressure vessels and piping, 71(2), 1997, pp. 169-173
In this present paper the stochastic finite element method (SFEM) is l
ed into the field of fracture mechanics and the cracked structures, wi
th random material properties and/or geometric parameters are analyzed
by the stochastic finite element method. The calculating formulae for
the mean and variance values of the J-integral are discussed leading
to an effective method for the probabilistic safety assessment of crac
ked structures. Meanwhile some elastic problems are solved by this met
hod and the numerical examples demonstrate that this method is appropr
iate for solving engineering problems and the related computer program
developed in this paper has sufficient precision. (C) 1997 Elsevier S
