principle strain Explanation: The mechanics of computing principal strains is identical to that for computing principal stresses. The only potential pitfall to keep in mind is that the equations always operate on one-half of the shear values, γ/2. The principal stresses are the corresponding normal stresses at an angle, θP, at which the shear stress, τ′xy, is zero. Hope it helps! -------------------------------------------------- Note added at 15 hrs (2017-03-24 12:27:37 GMT) -------------------------------------------------- Maximum and minimum normal strain possible for a specific point on a structural element. Shear strain is 0 at the orientation where principal strain occurs. Reference: http://continuummechanics.org/principalstressesandstrains.ht...
