Triaxial state of stress

WebStress is always simply F orce/Area F o r c e / A r e a , but some complexity does arise because the relative orientation of the force vector to the surface normal dictates the type of stress. When the force vector is normal to the surface, as shown at the right, the stress is called normal stress and represented by σ σ.
