Abstract

A new method for determining the proportional limit of engineering materials, characterized by maximum stress rate, is presented. Simultaneous measurement of stress rate and strain rate also permits a new means of measuring machine stiffness which has certain advantages over present techniques.

Keywords:
proportional limit, stiffness, tests, stress strain diagrams, elastic properties, mechanical properties, stresses, strain rate
