ELASTICITY

the ability of an object or material to resume its normal shape after being stretched or compressed; stretchiness.

TYPES

EX-SHEAR: Shear stress occurs whenever there is contact between two materials or components. In mechanics, shear forces are unaligned forces pushing one part of a body in one specific direction, and another part of the body in the opposite direction

COMPRESSIVE: Compressive stress is a force that causes a material to deform to occupy a smaller volume

Tensile Stress : When the material is under tension, it is known as tensile. The forces that are acting along the axis of force are responsible for the stretching of the material

STRESS: Stresses occur in any material that is subject to a load or any applied force.c

STRAIN : the degree of deformation that a material withstands in the direction of applied forces in relation to its original length

TYPES

VOLUMETRIC STRAIN:
The ratio of change in volume to original volume under normal loading condition is known as volumetric strain.

Longitudinal Strain:
The ratio of change in length to its original length in the direction of loading is known as longitudinal strain

SHEAR STRAIN:

When the shear stress is applied on a body, it tends to deform the shape of the body. The change in tangential angle in the direction of the loading is called shear strain.

HOOK'S LAW: Hooke’s law basically states that “when an object has a relatively small deformation the size of the deformation is directly proportional to the deforming load or force.”

MODULUS OF ELASTICITY: Modulus of elasticity is the measure of the stress–strain relationship on the object. Modulus of elasticity is the prime feature in the calculation of the deformation response of concrete when stress is applied

MODULUS OF RIGIDITY: Modulus of Rigidity - G - (Shear Modulus) is the coefficient of elasticity for a shearing force. It is defined aS the ratio of shear stress to the displacement per unit sample length (shear strain)"

APPLICATIONS

Most commonly, in everyday life, Hooke’s Law is applied in springs because of their elasticity.

They are used not only in the engineering field but also used in the field of medical science.

It is used in breathing (lungs), skin, spring beds, diving boards and cars suspension systems.

It is used as a fundamental principle behind the manometer, spring scale and balance wheel of the clock.

It is also used as the foundation for seismology, acoustics and molecular mechanics.
