The diagram shows the effect of 'sliding' an Edge (a), Screw (b), or Mixed (c) dislocation completely across a slip plane in the crystal. Each dislocation has the same effect as it moves completely ...

Minerals form the building blocks of almost everything on Earth. They are made up of crystals—regular, repeating atomic ...

· 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 ...

Scientists have expanded on a longstanding model governing the mechanics behind slip banding, a process that produces strain marks in metals under compression, gaining a new understanding of the ...

For decades researchers have studied materials from structures to see why and how they fail. Before catastrophic failure, there are individual cracks or dislocations that form, which are signals that ...

A new study led by the University of Liverpool examined olivine to better understand how it deforms. The researchers were surprised to find that about 17% of the crystals showed evidence of ...
