WebbStress Strain Curve . Proportional limit is the point on a stress-strain curve at which it begins to deviate from the straight-line relationship between stress and strain. See accompanying figure at (1 & 2). Elastic limit is the maximum stress to which a specimen may be subjected and still return to its original length upon release of the load. WebbdP dt = rP, P(0) = P0. This differential equation has an interesting interpretation. The left-hand side represents the rate at which the population increases (or decreases). The right-hand side is equal to a positive constant multiplied by the current population.

WebbHooke’s Law states that the strain of the material is proportional to the applied stress within the elastic limit of that material. Mathematically, Hooke’s law is commonly expressed as: F = –k.x Where F is the force, x is the extension in length, and k is the constant of proportionality known as the spring constant in N/m.
