121Résistance à la traction — Essai de traction courbe de traction typique d un matériau ductile Un essai de traction est une expérience de physique qui permet de mesurer le degré de résistance à la rupture d un matériau quelconque. Certains objets fabriqués par l homme… …
122Soudage (Théorie) — Cet article aborde le concept d énergie de soudage, afin de décrire et de quantifier quelques spécificités du soudage que sont les phénomènes locaux de fusion et de solidification ainsi que l écoulement thermique et les effets qui en résultent.… …
123copper — copper1 /kop euhr/, n. 1. a malleable, ductile, metallic element having a characteristic reddish brown color: used in large quantities as an electrical conductor and in the manufacture of alloys, as brass and bronze. Symbol: Cu; at. wt.: 63.54;… …
124deformation and flow — Alteration in size or shape of a body under the influence of mechanical forces. Flow is a change in deformation that continues as long as the force is applied. Gases and liquids normally flow relatively freely, while solids deform when subjected… …
125copper processing — Introduction use of smelting or leaching, usually followed by electrolytic refining or recovery, to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of copper and of its… …
126environmental works — ▪ civil engineering Introduction infrastructure that provides cities and towns with water supply, waste disposal, and pollution control services. They include extensive networks of reservoirs, pipelines, treatment systems, pumping stations …
127Christensen Failure Criterion — Failure criteria for isotropic materials has been a long standing problem. Despite many historical attempts, there have not been any successful general forms that span the range from ductile to brittle materials. A new failure criterion that aims …
128Ductility (Earth science) — In Earth science, the brittle ductile transition zone is a zone, at an approximate depth of 15 km (9 mi) in continental crust, at which rock becomes less likely to fracture and more likely to deform ductilely. In glacial ice this zone… …
