Application of the theory of strength of materials to determine the shear stresses in beams with round holes

Abstract

Abstract A study was carried out of the possibility of applicability of the theory of strength of materials to determine the shear stresses arising in sections weakened by perforation in the form of round holes, depending on the perforation parameters with a constant shearing force along the length of the beam. A method was proposed for the implementation of the Zhuravsky’s formula for a section weakened by round holes, in the form of dividing the cross section into two independent parts and determining the maximum shear stresses by methods of strength of materials. The reliability of this approach is confirmed by finite element analysis in the ANSYS Mechanical APDL software package. The results obtained can be used to determine the maximum shear stresses in perforated beams in cross-sections along the center of the cut.
