Interatomic Potential to Stress-Strain Lab

Choose a Lennard-Jones potential's well depth (ε) and equilibrium spacing (σ), pick a simple-cubic or close-packed crystal structure, then run a quasi-static tensile test on the resulting lattice. The live stress-strain plot shows exactly how those microscopic potential parameters set the macroscopic elastic modulus (its initial slope) and the fracture point (where the curve peaks and bonds start snapping) — save one parameter set as a dashed reference curve and compare it against another.
