we have tested that Absorbing the impulse hammer falling from a certain height
at that time we could calculate height after hammer smash
This calculating was needed hammer weight, potential energy, friction loss of energy
2.purpose of impact test
Impact test measures the energy absorbed on the force of the impact resistance of the material, or to measure the toughness test as fracture when the material is generally made on the specimen notch meeting Impulsively
Also measured the tensile strength of the existing experiments are essential experiments to evaluate the properties of materials that can not be represented, the groove or notch in the material when the fracture toughness of the event is to evaluate the stability of the structure.
However, the principle of shock-destructive testing of a relatively simple one, rotated so that the heavy pendulum is freely falling, and there are many restrictions on the practice.
For the purpose of the impact force of the impact test is to test the resistance of the material.
