Toughness is a term used to describe a material's resistance to failure, or its ability to absorb the energy of impact, if that is clearer. A couple of methods of testing toughness involve putting a (known) weight on a swinging arm, raising it a certain distance, and letting it swing down into a test piece of material into which a notch has been cut. This way a known amount of energy can be impressed against a sample of fixed dimension and a relative toughness demonstrated. In the physics department on exam day, we'd be given a stress-strain graph (or, more probably, the variables to plot the graph) and we'd "find the area under the curve" using integral calculus to discover an answer. The formula and the graphs (which cannot be put up here) can be seen by using the links to the Wikipedia articles. Additionally, a link is provided to a post on the Izod method of impact strength testing of plastics put up by MatWeb, which is a site dedicated to the properties of materials. Have a quick look.

How do you calculate fracture toughness from impact energy through impact test?
Impact test gives toughness value which is energy absorbed by material per unit volume.. From test like charpy test value of energy absorbed by the specimen can be calculated directly by getting the height of pendulum after impact.... whereas fracture toughness is totally different subject which comes into picture after formation of crack in the material. Methods of calculation of fracture toughness depends upon the type of material (brittle or ductile). Resistance curve is used to find the fracture toughness.
