OS1541 Fully automated parametric and propagation analyses on three-dimensional cracks by using an automatic meshing technique

Abstract

When crack analyses are performed for the structural integrity evaluations, the hexahedral elements are adopted in generally. It is very time consuming to build the finite element mesh using the hexahedral elements. Therefore, automated mesh generation by using the tetrahedral elements is adopted in present software system. Automated parametric analysis system from the meshing to the stress intensity factor computation can eliminate the manual operations completely. In this paper, automated parametric system is briefly described and a numerical example is presented.
