Define strain. Describe different types of strains with diagram.
Answers
Answer:
Explanation:
Strain is a measure of material deformation in response to an applied force (or stress). ... Moreover, as strain is a measurable deformation, when combined with a materials characteristic modulus, the applied force can be extracted. This is the principal of the strain gauge
Normal strain: It can be divided into three types. a. Tensile strain: When we apply a tensile force on a body its length increases. The ratio of increase in length to the original length. ... Compressive strain: When we apply a compressive force on a body its length decreases.
Answer:
Explanation:
When we apply a force on a body it will undergo deformation and its length will increase or decrease. Length increases when the force is tensile and decreases when the force applied is compressive.
The ratio of Change in dimension to the original dimension is called strain.
Strain = ε = Change in dimension/original dimension
There are two types of strains.
1. Normal strain (Tensile, compressive and volumetric)
2. Shear strain
Normal strain: It can be divided into three types.
a. Tensile strain: When we apply a tensile force on a body its length increases. The ratio of increase in length to the original length.
Tensile strain = εt = L – L0 / L
Where L = Original length
L0 = new length
b. Compressive strain: When we apply a compressive force on a body its length decreases. The ratio of decrease in length to the original length is called compressive strain.
Compressive strain = εc = L – L0 / L
Where L = Original length
L0 = new length
c. Volumetric strain: When we apply a force on all sides of a body its volume will decrease. The ratio of change in volume to the original volume is called volumetric strain.
Volumetric strain = εv = V – V0 / V
Where V = Original volume
V0 = new volume
Shear Strain: When we apply a tangential force on a body there is an angular displacement (θ), which measures the shear strain.
Shear strain = tan θ
