What is lateral stress and strain?

It occurs when under the action of a longitudinal stress, a body will extend in the direction of the stress and contract in the transverse or lateral direction (in the case of tensile stress).

How do you find lateral stress?

it is common to assume a K0 stress state, i.e. the lateral stress is the vertical stress multiplied by K0, where K0 is the earth pressure coefficient at rest. Jaky’s formula can be used to estimate K0 for normally consolidated soils: K0 = 1 – sin(phi), where phi is the friction angle.

What is lateral and axial strain?

εt is the Lateral or Transverse Strain. εl is the Longitudinal or Axial Strain. ν is the Poisson’s Ratio. The strain on its own is defined as the change in dimension (length, breadth, area…) divided by the original dimension.

What is the formula lateral strain?

E = 2 G ( 1 + v ) a n d E = 3 K ( 1 − 2 v ) Poisson’s ratio v being defined as the ratio of lateral strain to longitudinal strain and bulk modulus K as the ratio of volumetric stress to volumetric strain.

What is longitudinal stress?

Longitudinal stress is defined as the stress produced when a pipe is subjected to internal pressure. The direction of the longitudinal stress in a pipe is parallel to the longitudinal axis of its centerline axis, which means that the stress acts in the direction of the pipe’s length.

What is volumetric stress?

Bulk Stress or Volume Stress When the deforming force or applied force acts from all dimensions resulting in the change of volume of the object then such stress in called volumetric stress or Bulk stress. In short, when the volume of body changes due to the deforming force it is termed as Volume stress.

What is axial stress?

A stress that tends to change the length of a body. ♦ Compressive stress is axial stress that tends to cause a body to become shorter along the direction of applied force. Tensile stress is axial stress that tends to cause a body to become longer along the direction of applied force.

Is lateral same as transverse?

As adjectives the difference between lateral and transverse is that lateral is to the side; of or pertaining to the side while transverse is situated or lying across; side to side, relative to some defined “forward” direction.

Why is lateral strain negative?

It depends on the direction of the applied force. If the force stretches or expands the given dimension of the body then the strain is positive. If the force compresses the dimension of the body, the strain is negative. In the above example of cylinder, the linear strain is positive but the lateral strain is negative.

What is transverse stress?

The shear stress due to bending is often referred to as transverse shear. Like the normal stress there is a stress profile that is based off of the neutral axis of the particular cross-sectional area. This is due to the cross-sections width changing suddenly. …

What is longitudinal stress class 11th?

Longitudinal stress is defined as restoring force per unit area when the force is applied to the cross-sectional area of the cylindrical body. After it gets stretched its length increases by ΔL due to the stress. As there is change in the length therefore this type of stress is known as longitudinal stress.
