Abstract

Numerical verification of stress distribution ahead of crack tip for finite-width center cracked specimen C.H. Liu/ D.L. Chen/ H.A. Mang,' B. Weiss,* R. Stickler* * Institute for Strength of Materials, Technical University of Vienna, Karlsplatz 13/202, A-1040 Vienna, Austria * Institute of Physical Chemistry - Material Science, University of Vienna, Wdhringer Strasse 42, A-1090 Vienna, Austria ABSTRACT A force balance method, recently proposed for the calculation of geometric correction factors in conjunction with the stress intensity in finite-width specimens, assumed that the stress distribution ahead of the crack tip in a finite-width specimen has the same form as that in the corresponding infinite-width plate, modified by a geometric correction factor. In this pa- per the assumption is numerically verified by means of the finite element method for a center cracked specimen in different loading configurations. Close agreement between the finite element result
