Experiments in Material Testing and Experimental Stress Analysis

13.1 INTRODUCTION

At the undergraduate level, in the course of strength of materials/mechanics of solids, many tests are conducted such as hardness test, impact test, tensile test, compression test, etc. but at this stage we will discuss mechanical tests such an true-stress strain curve for a ductile material in tension, buckling test on column, creep test on a wire, fatigue test on rotating–bending specimen, and tests on experimental stress analysis techniques using photoelastic, strain gauges, and brittle coating techniques, etc.

Most important mechanical test is a simple tensile test on sample because this test provides a lot of vital information about mechanical behaviour ...
