SHEAR-STRENGTH OF A DUCTILE MATERIAL FROM TORSION OF SOLID CYLINDERS

The shear strengths of two ductile epoxies are obtained from solid cylinder torsion using a data reduction scheme. The results are in quantitative agreement with shear data from torsion of thin-walled tubes of the same materials, particularly with regard to the coincidence of the peak yield stress and strain. The described technique is useful for characterizing ductile material behavior in shear using a simple, solid cylinder specimen.
