The impact test is conducted by striking the specimen with a hammer on a pendulum arm, the test quantifies the absorbed energy during fracture under the impact load. Factors affecting material toughness include low temperatures, high strain rates (via impact or pressurization), and stress concentrators like notches, cracks, and voids. During N1 sleep, the body has not fully relaxed, though the body and brain activities start to slow with periods of brief movements. There are light changes in brain activity associated with falling asleep in this stage. It is easy to wake someone up during this sleep stage, but if a person is not disturbed, they can move quickly into stage 2.
The Charpy impact test (Charpy V-notch test) is used to measure the toughness of materials under impact load at different temperatures! Test setup and test procedure.
