Intrinsic toughening

WebThe novel lattice asymmetry induced intrinsic toughening mechanism discovered at the 2D limit shed important light into toughening of heterogeneous 2D materials. Main Text . If a material can withstand higher load without any irreversible damage, such as plastic Intrinsic toughening mechanisms are processes which act ahead of the crack tip to increase the material's toughness. These will tend to be related to the structure and bonding of the base material, as well as microstructural features and additives to it. Examples of mechanisms include • crack deflection by secondary phases, • crack bifurcation due to fine grain structure
