Definition of Strain: Strain is a measure of deformation, which gives the displacement between the particles in a material body. Strain is defined as the ratio of change in dimension to the original dimension of the material. In mathematical terms, strain (ε) is expressed as: ε = ΔL / L₀ Here, ΔLRead more
Definition of Strain:
Strain is a measure of deformation, which gives the displacement between the particles in a material body. Strain is defined as the ratio of change in dimension to the original dimension of the material. In mathematical terms, strain (ε) is expressed as:
ε = ΔL / L₀
Here, ΔL represents the change in length and L₀ represents the original length.
Why Strain Has No Units and Dimensions:
Strain is a dimensionless quantity because it is a ratio of two lengths (change in length to original length), which means that both numerator and denominator have the same units. Hence, the units cancel out, and one gets a unitless value. Since it is dimensionless, therefore it has no dimensions in the context of physical measurement.
Different Types of Strain:
1. Tensile Strain: It takes place when a material is stretched. It is defined as the change in length divided by the original length (elongation).
2. Compressive Strain: It takes place when a material is compressed. It is defined as the change in length divided by the original length (shortening).
3. Shear Strain: It is that strain which arises due to shear forces applied on a material. It is defined as the change in angle between two lines originally at right angles, expressed as the ratio of lateral displacement to the original length.
4. Volumetric Strain: It is the change in volume per unit original volume of a material, occurring under uniform pressure.
These types of strain are important for understanding how materials respond to various forces and deformations.
Definition of Stress: Stress is defined as the force exerted per unit area within materials. It results from external forces applied to an object, resulting in deformation. Mathematically, stress is represented as σ = F / A where σ is the stress F is the applied force and A is the cross-sectional arRead more
Definition of Stress:
Stress is defined as the force exerted per unit area within materials. It results from external forces applied to an object, resulting in deformation. Mathematically, stress is represented as
σ = F / A
where σ is the stress F is the applied force and A is the cross-sectional area over which the force is applied.
Units:
The SI unit of stress is Pascal (Pa), which is equivalent to Newton per square meter (N/m²).
Dimensions:
The dimensions of stress are represented as [M L⁻² T⁻²], where M is mass, L is length, and T is time.
Different Types of Stress:
1. Tensile Stress: This takes place when any material undergoes stretching or pull forces. The force per unit area along the direction of an applied force defines it.
2. Compressive Stress: It arises when compressive forces compress or squeeze the material. Force per unit area in a direction opposite to an applied force is defined by compressive stress.
3. Shear Stress: It happens when a material is subjected to forces that cause one layer of the material to slide over another. It is the force applied parallel to the surface divided by the area of the surface.
4. Volumetric Stress: This stress is due to changes in volume because of uniform pressure applied in all directions. It is significant in fluid mechanics and materials science.
Understanding these different types of stress is important in analyzing material behavior under various loading conditions.
