In construction field now, steel were used wildly. And mose not consider steel impact capacity. In some project that used steels be members may tumble down. According to this reason, this special project is aimed to test steel impact capacity of steels that have difference in tensile strength at many temp for studying and construction in the future.
Notch toughness is the measure of the resistance of a metal to the start and propagation f a crack at the base of a standard notch, commonly using the Charpy V-notch test. This test uses a small rectangular simply supported beam having a V-notch at midlength. The bar is fractured by a blow from a swinging pendulum. The amount of energy absorbed is calculated from the height the pendulum raises after breaking the specimen. The amount of energy absorbed will increase with increasing temperature at which the test is conducted.
