Stress – Strain Relationships Tensile Testing

One basic ingredient in the study of the mechanics of deformable bodies is the resistive properties of materials. These properties relate the stresses to the strains and can only be determined by experiment. One of the simplest tests for determining mechanical properties of a material is the tensile test. In this test, a load is applied along the longitudinal axis of a circular test specimen. The applied load and the resulting elongation of the member are measured.

Title: Tensile Testing of Metals

Objective: To determine the tensile strength of metals Introduction: Tensile testing is one of the most fundamental tests for engineering, and provides valuable information about a material and its associated properties. These properties can be used for design and analysis of engineering structures, and for developing new materials that better suit a specified use.

Introduction to Tensile Testing

Tensile Specimens. Consider the typical tensile specimen shown in . It has enlarged ends or shoulders for gripping. The important part of the specimen is the gage section. The cross-sectional area of the gage section is reduced relative to that of the remainder of the specimen so that deformation and failure will be Fig. 10 Improper (left) and proper (right) alignment of specimen attachment areas with axis of specimen

5. MECHANICAL PROPERTIES AND PERFORMANCE OF MATERIALS

Samples of engineering materials are subjected to a wide variety of mechanical tests to measure their strength, elastic constants, and other material properties as well as their performance under a variety of actual use conditions and environments. The results of such tests are used for two primary purposes: 1) engineering design (for example, failure theories based on strength, or deflections based on elastic constants and component geometry) and 2) quality control either by the materials producer to verify the process or by the end user to confirm the material specifications.

"Tensile Testing of Ductile Metals"

Objectives: To determine the followings 1. The relation between the engineering stress and engineering strain according to the results obtained from the tensile test. 2. The yield stress and offset yield stress. 3. Modulus of elasticity or young's modulus. 4. Tensile strength or ultimate tensile strength. 5. Percentage elongation and percentage reduction in area. 6. Indications to understand some important properties of material, such as ductility, brittleness and toughness.

Bogazici University Materials Science Course - Tensile Test Lab Report

The application of tensile load in increments until the failure of the material was the main purpose of this test. Change in the material's length was recorded after every increment. The data until the failure was recorded and used to find the material's yielding strength, ductility, tensile strength, toughness, true tensile strength, fracture strength, true fracture strength, modulus of elasticity and estimate its toughness. Then, an engineering stress-strain graph was plotted. Finally the conversion formulas were used to come up with the true stress-strain curve. The material's mechanic features were also compared with the theoretical results. The physical properties were in the expected interval.
