EAS 209-Spring 2011 Instructors: Christine Human 1/18/2011 1 Lecture 13 Lecture 13 Stress Concentrations / Circular Shafts Made of Elastoplastic Material The derivation of the torsion formula, J Tc max assumed a circular shaft with uniform cross- section loaded through rigid end plates. In addition, we assumed that Hooke’s Law applied throughout the material. Today’s Objectives: Consider stress concentrations in circular shafts with reduction in diameter Understand the behavior of an ideal elastoplastic material subjected to torsion. Today’s Homework: EAS 209-Spring 2011 Instructors: Christine Human 1/18/2011 2 Lecture 13 Stress Concentrations Use of f lange couplings, gears and pulleys, and cross-section discontinuities can cause stress concentrations. Stress concentration factors can be determined numerically or experimentally The figure opposite gives the stress concentration factor, K , for fillets in circular shafts with a reduction in diameter. The maximum stress is given by J Tc K max where Tc/J is the stress computed for the smaller diameter shaft.
