Mechanical Traction Tests of Different Types of Materials “Steel-Copper-Brass-Aluminum”

Abstract

The strain test is a physics experiment to measure the degree of resistance to breaking of any material. The strain test used to characterize materials, regardless of the form of the requested object, or the performance of a mechanical assembly. In this article we have made tests or pulling experience for different types of materials such as steel; Copper; Brass and Aluminum. This test involves placing a small bar of material to be studied between the jaws of a strain testing machine which pulls on the bar until it breaks. It records the elongation and the applied force, which is then converted into deformation and stress.
