WebSep 2, 2024 · The modulus of resilience is then the quantity of energy the material can absorb without suffering damage. Similarly, the modulus of toughness is the energy needed to completely fracture the material. Materials showing good impact resistance are generally those with high moduli of toughness. Figure 13: Moduli of resilience and toughness.

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.
