How do you explain stress and strain on a graph?
A stress-strain curve is a graphical way to show the reaction of a material when a load is applied. It shows a comparison between stress and strain. Stress is the ratio of the load or force to the cross-sectional area of the material to which the load is applied.
What is stress-strain curve explain it?
Stress strain curve is a behavior of material when it is subjected to load. In this diagram stresses are plotted along the vertical axis and as a result of these stresses, corresponding strains are plotted along the horizontal axis. As shown below in the stress strain curve.
What is difference between stress and strain?
Stress is a force acting on a rock per unit area. It has the same units as pressure, but also has a direction (i.e., it is a vector, just like a force). Strain is a change in shape or size resulting from applied forces (deformation). Rocks only strain when placed under stress.
What is the example of strain?
The definition of a strain is a bodily injury due to overexertion or an excessive demand on resources. An example of strain is a pulled muscle. An example of strain is reading a book in the dark, causing pressure on the eyes. To injure or impair by overuse or overexertion; wrench.
What is strain example?
Strain is defined as to exert or stretch to the maximum or to injure by too much exertion. The definition of a strain is a bodily injury due to overexertion or an excessive demand on resources. An example of strain is a pulled muscle. An example of strain is reading a book in the dark, causing pressure on the eyes.
What is stress and strain in engineering?
When a material is loaded with a force, it produces a stress, which then causes a material to deform. Engineering strain is defined as the amount of deformation in the direction of the applied force divided by the initial length of the material.
What is the basic difference between stress and strength explain briefly?
Stress is a measure of how much force an object experiences per unit area, and strength is a material’s ability to withstand stress. When the stress exceeds the strength of a part, it fails.
What is the difference between stress and strain?
The main difference between stress and strain is that stress measures the deforming force per unit area of the object, whereas strain measures the relative change in length caused by a deforming force.
What is the equation for stress and strain?
Stress Equation. Stress (sigma) is related to strain (epsilon) through the equation: sigma = E x epsilon. This relationship is only valid in regions where Hooke’s Law is valid.
What is the true stress strain curve?
True stress-true strain curves are often called flow curves, which represent plastic flow of the material. The flow curve is often used to determine two parameters characteristic of the material, the strain hardening exponent and the coefficient of the strength of the material.
What is the area under a stress/strain graph?
The area under the stress-strain curve is called toughness. If the upper limit of integration up to the yield point is restricted, the energy absorbed per unit volume is known as the modulus of resilience.
What is the ratio of stress and strain known as?
Explanation: The elastic modulus is the ratio of stress and strain. So on the stress-strain curve, it is the slope.
