Quasi-longitudinal waves are one type of structural waves, which areimportant at high frequencies. This paper studies the estimate theory and measure-ment techn
A mechanism of plastic flow localization in ductile matter near mi-crovoids is studied.The voids with the size-scale of micromillimeter exist in sheetspecimens
The gliding behavior of edge dislocation near a grain boundary(GB)in copper under pure shear stresses is simulated by using molecular dynamics(MD)method. Many-b
