An international team of researchers, led by University of Toronto Engineering Professor Yu Zou, is using electric fields to control the motion of material defects. This work has important ...
Recent experimental findings from the research team led by Prof. Jianbo Hu at the Institute of Fluid Physics, China Academy of Engineering Physics (CAEP), revealed partial dislocation-mediated plastic ...
Characterization of dislocation motion in the alloy using discrete dislocation dynamics (DDD) simulations. Video showing the effect of lattice strain field on the dynamic evolution of dislocations ...
· Dislocation motion in crystals can occur when a shear stress act across the slip plane. This is illustrated for an edge dislocation. · The atomic structure is only adjusted in the region of the ...
For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without breaking. Their secret lies in tiny, line-like defects called dislocations, ...
The energy of a dislocation depends on its position in its slip plane. The diagram represents a slip plane with a position dependent potential having a period, a, determined by the location of rows of ...
