It consists of a cylindrical specimen having a diameter of 0.5 ...
The stress-strain diagram differs in form for various materials. The diagram shown below is that for a medium-carbon structural steel. Metallic engineering materials are classified as either ductile or brittle materials. A ductile material is one having relatively large tensile strains up to the point of rupture like structural steel and aluminum, whereas brittle materials has a relatively small strain up to the point of rupture like cast iron and concrete. Stress Strain Diagram brittle Material . The diagram below shows Stress strain graph for a brittle and a ductile material. A typical brittle material is Cast Iron. Steels become increasingly brittle as the carbon content increases. Brittle fractures are generally clean and the ends of the test piece are sqaure and mate together. True Stress and Strain Developing a Stress–Strain Diagram Stress–Strain for Steel The first material we will discuss is: structural steel A stress–strain diagram for a typical structural steel in tension is shown: Elastic Plastic Strain Hardening Necking Fracture Ultimate Stress Yield Stress s Stress–Strain for Steel 0.05 0.10 0.15 0.20 0.25 20 40 60 Strain CIVL 1101 Introduction to Mechanics of Materials - Part 2 1/5 Alloy steel stress-strain diagram. The engineering tension test is widely used to provide basic design information on the strength of materials and as an acceptance test for the specification of materials. In the tension test a specimen is subjected to a continually increasing uniaxial tensile force while simultaneous observations are made of ...

Proportional limit. It is the limit at which material follows Hook's law and represents the maximum value of stress at which the stress-strain diagram is linear and within this limit, the ratio of stress to strain gives a proportional constant called Young's modulus. The line OA on a stress-strain diagram shows a proportional limit.
