“What happens when a shear stress acts upon a crystal lattice?”
Crystal lattices are prone to imperfections, such as line defects. However, what happens when the crystal pattern experiences a shearing effect? Well, let’s use our scientific mindset to investigate this issue. Well, this will cause a rupture in the geometry which will result in a phenomenon known as a screw defect. Screw defects are so named due to the fact that if one were to walk from one edge of the dislocation to the other without jumping or falling, a screw like path would be formed.
