WebNov 26, 2024 · These merit indices are easily used with the Toughness-Young's Modulus materials-selection map. The following method is used to derive the merit index (GC E)1 / 2. Consider stretching a material: the strain (or amount of stretching) of the material is given by the equation: ε = σ E. The amount of stretching at the fracture point is: 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 conditions at the tip of a crack with thin components having plane stress conditions and thick components … See more Fracture toughness varies by approximately 4 orders of magnitude across materials. Metals hold the highest values of fracture toughness. Cracks cannot easily propagate in tough materials, making … See more Intrinsic mechanisms Intrinsic toughening mechanisms are processes which act ahead of the crack tip to increase the material's toughness.
