.... This understanding is also important to gain insights into the role of scale in the preference between microcrack formation and precrack extension. In the present work, a relation between crack surface energy and grain size proposed by Rice and Freiman [( 25 )] is used. 9 γ = γ pc [ 1 - ( G...

Ruch In this study, nitrogen plasma treatment at atmospheric pressure was used to modify the surface of polylactic acid (PLA), especially its low surface energy and wettability, which do not favor the interface adhesion with another...

... target values that consist of important material properties obtained from experiments and first-principle calculations based on density-functional theory. The optimized target quantities include elastic constants, cohesive energies, surface energies, vacancy-formation energies, and the forces on atoms...

... then the surface area to the volume ratio increases considerably. In this case surface energy should be incorporated into the physics of the problem. This quantity is distinct from the bulk deformation dependent energy due to the different coordination numbers of the surface-interface atoms, different bond lengths...

... for a material permits computation of strain energy density for a specified value of stress or strain. The free energy for the ion-bombarded region, which forms the actual surface in an ion-bombarded solid, is lower than that of crystalline silicon by almost 25%. This reduction in surface energy is very...

... surface steps in our calculations. Using appropriate parameters from atomistic studies, the (100) orientation is found to be unstable under compressive strain; the surface energy now develops a new minimum at an orientation that may be interpreted as the (105) facet observed in Si Ge ∕ Si systems...
