description

In multiaxial fatigue analysis using the critical plane approach, the shear stress amplitude has to be evaluate using proper numerical procedures that elaborate the points of the curve described by the tip of the shear stress vector acting in the analyzed plane. The calculation has to be carried out in several planes centred in the analyzed material plane; furthermore, in the analysis of a component, it has to be repeated in several points. In this paper a procedure that allows to noticeably reduce both the number of planes and the number of points in which it is necessary to evaluate by means of the onerous procedures, with a considerable reduction of the computational times.
