Abstract

Proper functioning of mechanical systems can only be achieved if machine parts are properly dimensioned. Since dimensioning of machine parts is impossible without previous stress state analysis, the aim of this paper is to obtain the distribution of minimum principal normal stress in the case of uniaxial tension of rectangular steel plates with an elliptical opening. For purposes of research, results showing minimum principal normal stress distribution are obtained using analytical and numerical methods, wherein the latter are performed using the finite element software package ANSYS©.

Keywords: elliptical opening, minimum principal normal stress, rectangular plate, ANSYS© software
