STRAIN Strain is the measure of how much a material deforms when a load is applied to it, expressed in inches of deformation per inch of material length. For example, if the 1/2" diameter shaft supporting the 10,000 pound load in Figure 1 is 12" long, it will stretch about 0.020" (20 thousandths) from its unloaded length, which you can measure.

Quite often material test data are supplied using values of nominal stress and strain. In such situations you must use the expressions presented below to convert the plastic material data from nominal stress-strain values to true stress-strain values.

The stress-strain relationship for materials is given by the material’s stress-strain curve. Under Hooke’s Law. In the 19th-century, SUB: STRENGTH OF MATERIAL MODULE-17A JH ACADEMY Page 2 Hooke’s law: It states that when a material is loaded within elastic limit, the stress is proportional to the strain produced by the stress. This means the ratio of the stress is the corresponding strain is constant within elastic limit. this force into stress and the deformation into strain and we define these as follows. Strain is the deformation per unit of the original length Strain = = x/L The symbol is called EPSILON Strain has no units since it is a ratio of length to length. Most engineering materials do OPTI 222 Mechanical Design in Optical Engineering 20 As shown in the previous diagram, the initial portion of the stress-strain diagram for most materials used in engineering structures is a straight line. For the initial portion of the diagram, the stress σ is directly proportional to the strain ε.

Over the elastic region of the graph the deformation is direct proportional with the load. Dividing the load by the cross-section area (constant) and the deformation by the original length (constant) leads to a graphical representation of Strain vs. Stress. Stress and strain can be related in several different ways. But when engineers say “the stress-strain curve,” they mean a graph that results from a simple tensile test.

In this spirit with the consideration of the calculated Taylor's factor and the residual stress. The Ultimate Roark's now includes. New material.

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

Stresses are either tensile or compressive. Structural materials are chosen by their ability to resist We are interested in studying and comparing stress-strain curves of metals, ceramics and polymers (in terms of their chemical bonding). Key materials for A typical stress-strain curve during compression of a brittle material, such as concrete, is illustrated in the figure. Failure in compression is less catastrophic than Stress vs. Strain Curves. If you apply some stress to a material and measure the resulting strain , or vice versa, you can create a stress vs. strain curve like the Stress and strain, how to calculate them and their relationship.

The resulting stress-strain curve or diagram gives a direct indication of the material properties. Note: Stress-strain diagrams are typically based upon the original cross sectional area and the initial gage length, even though these quantities change continuously during the test.

In Portion AB of the graph, stress is not directly proportional to the strain of the material. Note that slope of graph is decreased; this means that strain increases more rapidly with strain. The point B is termed as Elastic limit.
