💥 Impact Test Calculator
Calculate impact energy, toughness, and fracture characteristics from impact tests
📐 Impact Test Formulas
Impact Energy = mg(h₁ - h₂)
Toughness = Impact Energy / Cross-sectional Area
Ductile-Brittle Transition = f(Temperature)
Fracture Energy = Work Done / Fracture Area
m = mass, g = gravity, h = height, T = temperature, A = cross-sectional area
💡 Tips
- Charpy test uses a V-notch specimen, Izod uses a cantilever specimen
- Impact energy decreases with decreasing temperature
- Ductile-brittle transition temperature is material dependent
- Higher impact energy indicates better toughness
- Standard test temperatures: -40°C, 0°C, 20°C, 100°C
- Consider strain rate effects on material behavior
