How does this simulation stay faithful to the 3D version?

It reuses the exact same elastic-plastic-fracture formulas as the 3D crystal-lattice simulator — Hooke's law below yield, a defect- and temperature-dependent yield strength, and the same fracture threshold — rendered as a flat row-and-column lattice instead of a 3D grid.

What do temperature and defect density change?

Both lower the yield strength: raising temperature softens the bonds, and raising defect density makes dislocations easier to nucleate, so the lattice yields and fractures at a lower applied stress.

Materials Engineering 2D: Crystal Lattice Under Stress

2D cross-section companion to the 3D crystal-lattice simulator: stretch a flat lattice of bonded atoms and watch it move from elastic stretch through dislocation slip to fracture, while a live stress-strain curve traces the same Hooke's-law-to-yield-to-fracture path engineers design against.

This is the 2D cross-section companion to the 3D crystal-lattice-under-stress simulator. It drives the same elastic-to-plastic-to-fracture model — Hooke's law below yield, a temperature- and defect-dependent yield strength, dislocation slip past yield, and fracture beyond that — through a flat row-and-column lattice of bonded atoms instead of an orbiting 3D grid, with a live stress-strain curve on the strip chart below tracing the exact same elastic ramp, plastic bend and vertical fracture drop that a real tensile test produces.
