Consider a three-dimensional state of stress characterized by: sxx = 20.69 syy = 13.79 txy = 0.0 szz
Consider a three-dimensional state of stress characterized by:
σxx = 20.69 σyy = 13.79 τxy = 0.0
σzz = 27.59 τzx = 0.0 τyz = 17.24
Where units are MPa and compression is positive. Find: the magnitude and direction of the principal stresses and illustrate with a sketch.
