TABLE OF CONTENTS Material properties depend on many variables and vary widely. The properties given here are approximate mean values. Elastic strength may be represented by yield stress, proportional limit, or offset yield stress. Both elastic strength and ultimate strength refer to tensile strength unless stated otherwise.
