It is referring to whether the material tears, rips, or breaks easily. If it is tough material it is strong.
Tool steels are compared to each other. They are usually measured by toughness, hardness and wear resistance. The toughness is detemined by an Charpy impact test. The hardness is measured by a Rockwell hardness tester and reported as HRC or RC. The wear resistance is measured by a number of tests that measured the amount of material removed from the original size after a repetitive movement against an abrasive material. These figures are then gathered and presented on a chart. The grades are then compared with one another based on these three properties. See the links below for more information on comparing tool steels.
Impact test determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material's toughness and acts as a tool to study temperature-dependent brittle-ductile transition. It is to determine whether the material is brittle or ductile in nature.
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.

Toughness from impact test is a measure of a material's ability to absorb energy during sudden loading, while toughness from tensile test is a measure of a material's ability to deform plastically before fracturing under a slowly applied load. Impact toughness is important for assessing material behavior under dynamic loading conditions, while tensile toughness provides insight into material behavior under static loading conditions.

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.
Yes, diamonds are the hardest known natural material on Earth with a Mohs hardness scale of 10. However, it is important to note that hardness and toughness are two different properties. Toughness refers to a material's ability to resist breaking or shattering under force, and in this regard, some materials like metals may exhibit better toughness than diamonds.
To determine the toughness of a solid, you would need to know its tensile strength, yield strength, and elongation at break. Toughness is a measure of a material's ability to absorb energy before fracturing, and it depends on a combination of these properties.
It is the English units for Fracture Toughness (K1c) of a specific material.
Combines the strenght and rigidity acrylonitrile and styrene polymers with the toughness of polybutadiene rubber.
Toughness is the ability of steel to absorb energy. Hardness is the ability of steels to withstand wear. Hardness is the ability of material to withstand the indent and is measured in rockwel or vickers. also it is a measure of stiffness of material. but hardenability is ability of material to become hardened by various methods of hardening such as carburising or quenching. it is firmly dependent on quantity of carbon in that material. and actually it doesn't have any measuring unit !
Both the properities are having the ability to absorb the energy,but they differ in elastic properity,If the same amount of energy being absorbed by the materials having mechanical properity of toughness and stiffness,The elastic range of tough material is more ,than the stiff material when compared.Spring material is tough,but Low carbon mild steel with annealed heat treatment if stiff,Hence the difference can be made between them,
When asked to do a toughness test you roll one die and compare it to the models toughness. You pass if you are equal to or less then your stat. a roll of a 6 always fails this test.
