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. WebHere, load-reload triaxial compression tests are used to investigate damage development at low and high effective pressures, ... Results illustrate that contours of equivalent damage for sub-critical stress states between yield and macroscopic failure are sub-parallel to the failure envelope across the brittle-ductile transition.
