Abstract:

The improved endochronic theory of plasticity is applied to the case of a solid bar with circular cross section subjected to cyclic fully-reversed torsional loading. Numerical techniques are employed to obtain the solution. The parameters of the constitutive equations are determined from the test data of thin-walled specimens. These parameters are then used without alteration to compute stress distributions within the solid specimen. The relation of torque vs. strain at the outermost fiber of the solid specimen provides an ultimate check of this theory. This paper demonstrates an expanded use of the improved theory. Author
