WebStrain is a unitless measure of how much an object gets bigger or smaller from an applied load.Normal strain occurs when the elongation of an object is in response to a normal stress (i.e. perpendicular to a surface), and is denoted by the Greek letter epsilon.A positive value corresponds to a tensile strain, while negative is compressive.Shear strain occurs when … WebPrincipal Strain Directions, Deformation Ellipses, and Ellipsoids. One can use v and λ in order to depict deformation directions of a unitary circumference (in 2D) or a sphere (in 3D) as shown in Figure 5, conveniently rescaled if necessary, and the principal axes of the resulting ellipses (or ellipsoids in ℝ 3).
