Tensiones en ejes huecos con una grieta superficial bajo flexión rotativa

Abstract

Hollow axis are widely used in all branches of

industry and bear great responsibility. Their

behaviour under fatigue being nonetheless well

known, and the crack growth phenomenon

extensively studied, the understanding of the

physical phenomenon somewhat lacks theoretical

backing. Moreover, it is still to be explained why

hollow axis behave, under fatigue, differently to

whole ones. The present paper gives a start to the

theoretical study of the stresses in a hollow axis

in flexural mode, considering the variations of its

strength moment and its nominal tractive efforts,

showing that these endure oscillations harsher

than those usually attributed to these cases.
