Original Abstract

Main goal of this paper is to show the own-programmed procedure, based on the support of Java programming language. This automatic procedure contains parametric input; creation of FE model of considered test configuration (with variable crack length) in ANSYS system; its calculation; output of chosen nodal displacement (plenty of possibilities which differ in selection of the distance from the crack tip, the angle and/or their ranges); application of ODM to obtain values of coefficients of terms of Williams expansion or the corresponding dimensionless shape functions. This single tool should save time for further data evaluation.
