Step 1
The orientation of the principal planes can be determined by finding the angle at which the maximum normal stress occurs. This can be done using the formula: θ = 0.5 * atan(2 * τxy / (σx - σy)) θ = 0.5 * atan(2 * 3 ksi / (14 ksi - 5 ksi)) θ = 0.5 * atan(6 ksi / Show more…

For the state of plane stress shown, determine: a. the principal stresses and the maximum shear stress and the orientation of the planes on which they act. b. Using Mohr's Circle, verify the answers in part a. c. If the material is a structural steel ASTM-A36; E=200 GPa; v = 0.33, determine the principal strains and maximum shear strain.

[3] Components of the stress tensor ̃σ at a point, with respect to the (x, y, z) coordinate system, are given as ̃σ = [18 24 0; 24 32 0; 0 0 20] (MPa). (a) Find the principal invariants of ̃σ . (b) Find the principal stresses σ_i and the unit vectors ê_i along the principal directions. Arrange σ_i such that σ_1 ≥ σ_2 ≥ σ_3 . choose the senses of ê_i such that ê_1 ⋅ ê_2 × ê_3 = +1. (c) Find the maximum shear stress |σ_s|max and the normals to the planes on which |σ_s|max acts. Express the normals in terms of the unit vectors (i', j', k').
