Use of Reissner's Variational Principle in Finite Element Analysis of Crack Problems.
Abstract
For the purpose of accurately estimating linear elastic fracture parameters by finite element method, the use of Reissner's variational principle as a basis is investigated. Results of two-dimensional analyses performed on three-point bend, compact tension, and ring tension geometries compare well with other solutions available in the literature. Results of three-dimensional analyses of three-point bend and ring geometries are also presented. The method appears to be particularly useful in studying through the thickness variation or Mode I stress intensity factors. (Author)
