The materials with low fracture toughness that are susceptible to rapid crack growth failure are relatively brittle materials, such as: • Glass and ceramics • Hard steels • Strong aluminum alloys • Titanium alloys
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 … See more In materials science, fracture toughness is the critical stress intensity factor of a sharp crack where propagation of the crack suddenly becomes rapid and unlimited. A component's thickness affects the constraint … See more Fracture toughness varies by approximately 4 orders of magnitude across materials. Metals hold the highest values of fracture toughness.
