## How do you explain stress-strain curve?

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 and strain PDF?**

Stress is defined as, the deformation force per unit area of the body or material. Stress is the internal force(per unit area) associated with the strain. It is ratio of force applied on the system to the per unit area of the body. To find the stress of an object which is displaced (after applying force on it).

### What is strain explain?

Strain is the amount of deformation experienced by the body in the direction of force applied, divided by the initial dimensions of the body.

**What is stress and strain and its types?**

Stress – Definition And Types. In physics, stress is the force acting on the unit area of a material. The effect of stress on a body is named as strain. Stress can deform the body.

#### How do you calculate stress strain?

Stress is defined as the force per unit area of a material. i.e. Stress = force / cross sectional area: Strain is defined as extension per unit length. Strain = extension / original length. Strain has no units because it is a ratio of lengths. How do you calculate load stress? We calculate the stress, using the stress formula: σ = F/A = 30

**What is the true stress strain curve?**

When Tensile force is applied,engineering stress is always less than the corresponding true stress.

## How do you explain a stress strain graph?

– We plot a graph between the stress and strain and a curve is obtained. This curve so obtained is called the stress strain curve or stress strain diagram. – The stress strain diagram for the same material is different for different temperature and loading condition of the material. – In the graph the slope represents the young’s modulus of the material.

**How to read a stress strain curve?**

Stress strain curve is the plot of stress and strain of a material or metal on the graph. In this, the stress is plotted on the y-axis and its corresponding strain on the x-axis. After plotting the stress and its corresponding strain on the graph, we get a curve, and this curve is called stress strain curve or stress strain diagram.
