Interactive tools for understanding how materials respond to mechanical loading — from stress–strain behavior and failure criteria to multiaxial stress states and standardized test methods.
Compare engineering and true stress–strain curves for 13 materials across 4 classes. Toggle resilience, toughness, yield markers, and the 0.2% offset line. PMMA updates live with temperature.
Visualize the 2D stress tensor on a rotating stress element. Mohr's circle updates live — find principal stresses, max shear, and the von Mises equivalent stress interactively.
Five animated test methods: tensile, Charpy/Izod impact, creep, stress relaxation, and fatigue. Live curves, animated specimens, and material comparisons across metals and polymers.
Animated indentation tests for Brinell, Vickers, Rockwell, and Shore Durometer methods. See indenter geometry, indent size, formulas, and hardness scale comparisons for metals and polymers.
