What is Impact strength? - Definition from Trenchlesspedia

WebExplanation: Brittleness is inversely proportional to the value of impact strength of the body that is more the impact strength less is the brittleness and vice versa. 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.
