  • A load is applied on the material
  • The material tries to resist this load, which then generates stress within the material
  • That stress is the resistance of the material to being torn apart by the load
  • A material could be torn apart either perpendicular to its cross-section or parallel to its cross-section
  • Stress that resists being torn apart perpendicular to the cross-section of the material is Normal Stress
  • Stress that resists being torn apart parallel to the cross-section of the material is Shear Stress

  • Stress is still a general concept of internal resistance to the applied load, regardless of the type of that loading (force, torsion, moment)
