The theory supposes that the process controlling catastrophic fracture is the growth of a crack from a grain boundary pore with an energy absorption rate corresponding to the grain boundary surface energy of 10 3 erg/cm 2 . In practice, the process controlling catastrophic fracture is the ...
Strain is a crucial measure of materials deformation for evaluating and predicting the mechanical response, strength, and fracture. The spatial resolution attainable by the modern real and reciprocal space techniques continues to improve, alongside the ability to carry out atomistic simulations. This is...
Strength of materials Peter A. Claisse, in Civil Engineering Materials, 2016 2.4 Strain In engineering, strain is not a measure of force, but is a measure of the deformation produced by the influence of stress. For tensile and compressive loads: (2.5)Strain= Increase in length xOrig...
The strength of materials depends on the rate at which they are tested, as defects, for example dislocations, that move in response to applied strains have intrinsic kinetic limitations1,2,3,4. As the deformation strain rate increases, more strengthening mechanisms become active and increase the ...
In subject area: Materials Science Dynamic strain aging (DSA) occurs at combinations of strain rate and temperature at which the (interstitial) solutes can just keep pace with the dislocations. From: Structural Alloys for Nuclear Energy Applications, 2019 ...

A new energy-based fatigue damage parameter in life prediction of high-temperature structural materials Anew life prediction model has been developed with the energy-based fatigue damage parameter of a non-dimensional plastic strain energy density (PSED). Ten... KO Lee,SG Hong,SB Lee - 《Mater...
The 'Effect of Strain' refers to the quantification of the interaction energy among carbon impurities based on the distribution of strain in a given configuration. It can be defined by comparing the total energies of the clean surface and the system with carbon impurities in different configurations...
Strain usually exists in conjunction with ligand effect, which can modify the electronic structure and surface adsorption strength of the material, thus effectively regulating the OER activity of the material. Currently, intrinsic strain is usually applied to materials by using lattice mismatches between...
