WebThe toughness of a material is the maximum amount of energy it can absorb before fracturing, which is different from the amount of force that can be applied. Toughness … george orwell burma policeIn materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing. Toughness is the strength with which the material opposes rupture. One definition of material toughness is the amount of energy per unit volume that a material can absorb … See more Toughness is related to the area under the stress–strain curve. In order to be tough, a material must be both strong and ductile. For example, brittle materials (like ceramics) that are strong but with limited ductility are not … See more Toughness can be determined by integrating the stress-strain curve. It is the energy of mechanical deformation per unit volume prior to fracture. The explicit mathematical … See more Tensile toughness (or, deformation energy, UT) is measured in units of joule per cubic metre (J·m ) in the SI system and inch-pound-force per cubic inch (in·lbf·in ) in US customary units. 1.00 N·m.m ≃ 0.000145 in·lbf·in and 1.00 in·lbf·in ≃ 6.89 kN·m.m .
