Discussion on impact strength
The charpy impact test is one of the impact-testing that is used to determine the resistance towards a sudden load or impact impacted specimens with small fracture or with a very little plastic deformation is said to be in a brittle manner whereas fracture of a metal after extensive plastic deformation is said to be in a ductile manner. Small studies can also make use of surrogate markers when examining associations, ie a factor that can be used instead of a true outcome measure, but it may not have an obvious impact that subjects are able to identify for example, in lung cancer, the true end-point in a clinical trial of a new intervention is overall survival: time until. Impact strength index, slake durability index and uniaxial compressive strength (ucs) are important properties of a rock mass which are used widely in geological and geotechnical engineering.
