Seeing Stress With Supercomputers

Supercomputer simulations show that at the atomic level, material stress doesn't behave symmetrically. Molecular model of a crystal containing a dissociated dislocation, atoms are encoded with the atomic shear strain. Below, snapshots of simulation results showing the relative positions of atoms in the rectangular prism elements; each element has dimensions 2.556 Å by 2.087 Å by 2.213 Å and has one atom at the center.
