Stress and Strain: Definition, Formula,Types in detail, [Notes & PDF]
It is measured as the external force applying per unit area of the body i.e, 1. Stress = External deforming force (F)/Area(A) 2. Its SI unit is Nm-2 or N/m2. 3. Its dimensional formula is [ML-1T-2]. See more
There are mainly 3 types of stresses: 1. Tensile stress 2. Compressive stress 3. Tangential stress Tensile stress: Tensile stress is defined as … See more
Strain is defined as the change in shape or size of a body due to deforming force applied on it. We can say that a body is strained due to stress. See more
Strain also have 3 types: 1. Longitudinal strain 2. Volumetric strain 3. Shearing strain Longitudinal strain: When the deforming force … See more
Its symbol is (∈). Strain is measured by the ratio ofchange in dimension to the original dimension. i.e, Since it is ratio of two similar quantities, it is a pure number. Therefore, Strain has no SI unit. It is dimensionless. See more

Stress–strain curve - Wikipedia
In engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strain. It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing). These curves reveal many of the properties of a material, such as the Young's modulus, the yield strength and the

Stress, Strain and Young's Modulus - The Engineering …
Stress is force per unit area - strain is the deformation of a solid due to stress. Stress is the ratio of applied force F to a cross section area- defined as " force per unit area ". Tensile or compressive stress normal to the plane is usually …
Stress (mechanics) - Wikipedia
In continuum mechanics, stress is a physical quantity that describes forces present during deformation. For example, an object being pulled apart, such as a stretched elastic band, is subject to tensile stress and may undergo elongation. An object being pushed together, such as a crumpled sponge, is subject to compressive stress and may undergo shortening. The greater the force and th…
