Toughness comes from a blend of high strength and ductility, and it varies depending on the details of a structure, even if the material itself doesn't change. FromScience Magazine People have long coveted ivory for its beauty, ductility and presumed magical properties. ...
The concrete quantity poured involved 100,000 cubic metres (3,500,000 cu ft) of non-reinforced bulk concrete and 10,000 cubic metres...- Reinforced concrete, also called ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated......
Tensile, by its meaning, refers to the ability of steel drawn out. Tensile strength is the resistancepowerof the steel to break under the tensile strain. It is used in specifying the point where the steel transforms from an elastic form to a plastic form. It is usually measured in theunit...
PhysOrg.com - latest science and technology news stories 2009 The history of Athens demonstrated the weaknesses of a direct democracy, namely the susceptibility to demagoguery or “rabble rousing” rhetoric, and the founders considered it mob rule, but in the 19th Century, there was a widespread...
The malleability and ductility of a material are directly proportional to plasticity of the material. For an ideal plasticity property of material, it is to undergo irreversible deformation without any increase in load or stress. Fracture or rupture of the material may be caused by plasticity. Plas...
