Hello and thank you for replying. I am doing a research project related to power transmission shafts and unlike others, I don't want to ignore the shear stresses generated by the forces acting on the shaft. I have already done the analysis in terms of static stresses and deformations, however...
"The stresses acting on a structural element subjected to axial, shear or torsional loads are constant and do not change sign throughout the loading cycle. Therefore, alternating stresses, which cause fatigue, do not occur in these cases. On the other hand, in a beam subjected to bending load...
