What are the features of a stress strain graph?

A stress-strain graph gives us many mechanical properties such as strength, toughness, elasticity, yield point, strain energy, resilience, and elongation during load. It also helps in fabrication.

What are the characteristics of the elastic region of a material?

What is the elastic region? It is the region where the material can be deformed and when released will return back to its original configuration. Many metals in the elastic region have a resulting strain that is proportional to the tensile load when the applied tensile load is small.

How do you identify a material from a stress-strain curve?

A material’s Stress/Strain Curve is typically determined by testing a ‘dog-bone’ specimen of the material (as seen in Figure 3) of the material in question with a Tensile Strength Testing Machine, or TSTM.

What are the different types of stress and strain?

Stress, strain and its type

• Stress and strain.
• Types of stresses and strains.
• Tensile stress.
• Tensile strain.
• Compressive stress.
• Compressive strain.
• Shear stress.
• Shear strain.

What are the different types of strain?

In response to stress, rock may undergo three different types of strain – elastic strain, ductile strain, or fracture.

• Elastic strain is reversible. Rock that has undergone only elastic strain will go back to its original shape if the stress is released.
• Ductile strain is irreversible.
• Fracture is also called rupture.

What is strain write types of strain?

Types of strain : Strain is of three types. They are : 1) Longitudinal strain 2) Tangential. strain or Shear strain 3) Volumetric strain. Longitudinal strain : The ratio of elongation. to original length along length wise direction.

What is the difference between elastic region and plastic region as applied to a stressed material?

Elastic deformation is the deformation that disappears upon removal of the external forces causing the alteration and the stress associated with it. Plastic deformation is a permanent deformation or change in shape of a solid body without fracture under the action of a sustained force.

Why stress is dependent on strain?

In stress-strain curve as strain or the deformation is independent and comes as result of the externally applied force, so it is taken in X-axis. Where as Stress comes in order to resist the deformation in terms of Resisting force. so it is dependent on strain and comes in Y-axis.

How do you determine the toughness of a stress-strain curve?

Therefore, one way to measure toughness is by calculating the area under the stress strain curve from a tensile test. This value is simply called “material toughness” and it has units of energy per volume. Material toughness equates to a slow absorption of energy by the material.

What is stress and strain name the different types of stress and strain?

It is of two types: tensile and compressive stress. (Tangential stress: When the elastic restoring force or deforming force acts parallel to the surface area, the stress is called tangential stress.

What three factors determine the type of strain that stress will cause to rocks?

There are three types of stress: compression, tension, and shear. Stress can cause strain, if it is sufficient to overcome the strength of the object that is under stress. Strain is a change in shape or size resulting from applied forces (deformation). Rocks only strain when placed under stress.
