The specific reactions vary amongst individuals but there are consistent patterns. The stress-strain diagram is of immense help in conveying information about mechanical properties and behaviour of the material. We shall restrict ourselves to behaviour of structural steel only. Our interest on structural steel stems out from the fact that, it is one of the most widely used metals, being used in buildings, bridges, towers Did you know that the typical stress-strain curve obtained from a uniaxial tensile test is just an approximation?

From the perspective of loading, stress is the applied force or system of forces that tends to deform a body. The material's stress-strain curve represents the relationship between stress and strain for materials. The strain values are plotted on the curve corresponding to the … Plane stress and plane strain conditions are limit-case idealizations that are rarely met in a rigorious way by real world engineering problems. Nevertheless, many scenarios do come quite close.

E = σ/ε (normal stress – strain) G = τ/γ (shear stress – strain) Relation between Stress and Strain Hooke’s Law: “Within Elastic limit the ratio of stress applied to strain developed is constant”. The constant is known as Modulus of elasticity or Young’s Modulus or Elastic Modulus. Explaining Stress-Strain Graph.

To ascertain whether a structural member has adequate load-carrying capacity, the designer generally has to compute the maximum unit stress produced by design loads in the member for each type of internal force—tensile, compressive, or shearing— and compare it with the corresponding allowable unit stress. So, now you know all about engineering stress-strain curves.Normally I write these articles to stand alone, but in this case, I’ll assume you’re here because you googled a homework question 🙂 If you don’t understand the basics of the stress-strain curve, I recommend reading that one first.. So, what is the difference between engineering and true stress-strain curves?

Some tendons have a high collagen content so there is relatively little strain, or length change; others, like support tendons (as in the leg) can change length up to 10%. Note that this stress-strain curve is nonlinear, since the slope of the line changes in different regions. Stress – Strain Curve: Stress – Strain curve is the plot of the curve in XY Coordinate taking stress as Y axis and strain as X axis. It is the curve of the stress and strain of the body from zero to until the failure of the body. To plot this graph engineers will need the data of the stress and strain of … Stress and Strain The internal forces in a body will vary from one point to the other. Across any small internal plane area, loads are exerted by the part of the body on one side of … STRESS STRAIN ANALYSIS. RELATION B/W STRESS AND STRAIN : Following are the assumptions made in the stress strain analysis: 1.Material is homogeneous.

Chapter 6, is expanded, presenting more coverage on electrical strain gages and providing tables of equations Transformation of Stresses and Strains David Roylance Department of Materials Science and Engineering Massachusetts Institute of Technology Cambridge, MA 02139 So, now you know all about engineering stress-strain curves.Normally I write these articles to stand alone, but in this case, I’ll assume you’re here because you googled a homework question 🙂 If you don’t understand the basics of the stress-strain curve, I recommend reading that one first. The formula for Young’s Modulus is E=Stress/Strain. It measures the tensile elasticity of an object when stress is applied to it. For most metals that are stressed in tension at relatively low levels, strain and stress are proportional to each other. This general rule is known as Hooke’s law. strain is a measure of the change in the shape of the object that is undergoing stress and elastic modulus is a measurement of the amount of stress needed to change the shape of the object. There are three main types of stress.

One of the simplest tests for determining mechanical properties of a material is the tensile test. Strain is dimensionless quantity which expresses a proportional dimensional change (intensity or degree of the distortion) and is measured as the total deformation (elongation) per reference length of material due to some applied stress. The stress-strain behaviour in tension is similar to that in compression.
