There are several types of impact testing:
1. Charpy Impact Test: This test measures the energy required to fracture a test specimen by a swinging pendulum.
2. Izod Impact Test: This test measures the energy required to fracture a test specimen by a swinging hammer.
3. Drop Weight Impact Test: This test drops a weight onto a test specimen to measure its resistance to impact.
4. Instrumented Impact Test: This test uses high-precision sensors to measure the force and displacement of a test specimen during impact.
5. Tensile Impact Test: This test measures the resistance of a test specimen to impact while it is under tension.
6. Shear Impact Test: This test measures the resistance of a test specimen to impact while it is under shear stress.
7. Fatigue Impact Test: This test measures the resistance of a test specimen to repetitive impact loading.
