Toughness property

WebA material Toughness resists high impact or sudden load. Mathematically toughness is the energy absorbed per unit volume up to material fracture points. The area under the stress-strain curve till the fracture point is known as the toughness of a material. Tough materials have applications where the part has to bear a high impact load. WebRegarding toughness property evaluation, Charpy sub-size specimens (approximately 4 × 10 × 55 mm 3) were machined from the central part of the plane strain compression samples, and Charpy tests were carried out within a −120 to 40 °C test temperature range (Tinius Olsen Model Impact 104 pendulum impact tester with maximum capacity of 410 J).
