WebTangent Modulus – Slope of the stress-strain curve above the proportional limit. There is no single value for the tangent modulus; it varies with strain and describes the hardening of the material. Poisson’s ratio – The ratio of lateral or transverse strain to the longitudinal strain of an uniaxial load case. Poisson’s ratios ranges ... WebStress is given by the following formula: σ = F A where, σ is the stress applied, F is the force applied and A is the area of the force application. The unit of stress is N/m 2.
