WebStrain in mechanics measures the deformation in a material when mechanical stress is applied. Mathematically mechanical strain is equal to the ratio of change in length to the original length. Strain is a dimensionless quantity. It is denoted by “ε”. Let’s understand strain in context to external force and stress applied. WebMechanical Stress is a measure of internal resistance exhibited by a body or material when an external force is applied to it. it is denoted by sigma (σ). The elastic limit of the material is the limit where resisting force becomes …

Weblength L of the bar, then the elongation per unit length is called strain = C (normal strain : associated with normal stress) L tensile strain : positive compressive strain : negative strain is a dimensionless quantity, it is recorded in the form as mm/m, m/m, in/in e.g. L = 2 m, = 1.4 mm 1.4 x 10-3 m WebStrain hardening is one of the most commonly used means of adding strength to an alloy. It is simply the use of permanent deformation to increase the strength of the metal. Other names for strain hardening are cold work and work hardening. No discussion of strain hardening would be complete without mention of the term “temper”. how to evolve gengar
