WebHardness and toughness are material properties than sound similar in layman’s terms but are in fact two distinct scientific measures. Tough materials are those that are resistant to fracturing, measured by the amount of breaking energy they can withstand. Hardness, on the other hand, is how much a material can withstand scratches, cuts, or ... Fracture toughness tests are performed to quantify the resistance of a material to failure by cracking. Such tests result in either a single-valued measure of fracture toughness or in a resistance curve. Resistance curves are plots where fracture toughness parameters (K, J etc.) are plotted against parameters characterizing the propagation of crack. The resistance curve or the single-valued fracture toughness is obtained based on the mechanism and stability of fracture. F…
