Stress Concentrations Around a Small Spherical or Spheroidal Inclusion on the Axis of a Circular Cylinder in Torsion

Abstract

Abstract Stresses are calculated for the case of a small elastic inclusion bonded (i.e., continuous displacements and tractions across the surface of the inclusion) to a large circular cylindrical shaft. The inclusions considered are of spherical and spheroidal shapes. The results are discussed for several particular cases.
