Fracture toughness and young's modulus
WebFracture strength is the value corresponding to the stress at which total failure occurs. Stiffness is how a component resists elastic deformation when a load is applied. Hardness is resistance to localized surface deformation. Normal Strain: deformations that occur perpendicular to the cross-section; normal strain is caused by normal stress.
