Toughness definition: the quality or an instance of being tough | Meaning, pronunciation, translations and examples Hardness and toughness are properties related to materials which are generally used in material engineering. { Advertising GD&T Training Geometric Dimensioning Tolerancing Modulus of toughness is the total area below engineering stress-strain curve. describes the way a material Where ? exactly this type of sample There are several measurements of hardness, to … This book contains lots of information about the relationship between fracture toughness and strength. For the term toughness may also exist other definitions and meanings , the meaning and definition indicated above are indicative not be used for medical and legal or special purposes . Toughness definition. Simple toughness tests use specimens of fixed size with a machines notch, and just measure energy needed to break the specimen. Fracture toughness is an important consideration in hydraulic fracture design. Information and translations of toughness in the most comprehensive dictionary definitions resource on the web. This means that a material can undergo elastic deformation, or a deformation that allows it to return to its original form, without fracturing. // --> Toughness is measured by the Charpy test or the Izod test. Search engineering dictionary: Definition: Toughness. if (document.getElementById("tester") != undefined) from the upward swing of the pendulum after it has fractured Engineering design glossary of terms Design terms . Toughness is the ability of a material to absorb energy and plastically deform without fracturing. test or the Izod test. These two standardized impact tests, the Charpy and the Izod, are used to measure the impact energy (sometimes also termed notch toughness). { What ? Toughness It is the ability of a material to absorb the energy and gets plastically deformed without fracturing. toughness noun [U] (STRENGTH) C2 the quality of being strong and not easily broken or damaged: The toughness of the cast iron furnaces is remarkable.
