Forming limit curves (FLC) of deep drawing steel sheets have been determined experimentally and calculated on the base of the material tensile properties following the Hill, Swift, Marciniak-Kuczyński and Sing-Rao methods. Only the FLC modeled from a singly linear forming limit stress curve exhibits good consistence with experimental curve. It was established that a linearized limit stress locu...

Los estudios acerca de las élites y el perfil los gabinetes son muy vastos; sin embargo, pocos quienes han estudiado fenómeno desde una perspectiva com- parativa. En este artículo analizaremos Gobiernos con empresarial en América Latina durante período 2000-2019. Tomamos casos Mauricio Macri Argentina, Michel Temer Brasil Vicente Fox México; Sebastián Piñera Chile, Álvaro Uribe Colombia, Elías ...

background & objectives: streptozotocin (stz) is used for induction of type-1 diabetes mellitus in animal models. its beta-cytotoxic action results in sudden release of insulin leading to severe hypoglycaemia and even mortality. however, its sensitivity varies with species. present investigation was aimed at studying stz induced acute clinical effects in rabbits. methods: streptozotocin@ 65...

In the automobile industry, bending and hemming processes are normally used to supplement car body panels. However, Forming Limit Curve (FLC) inappropriately induces predict bendability in process as it has a different failure mechanism deformed sheet metals can undergo greater than predicted by FLC. this work, newly developed Bending (BLC) based on strain stress were experimentally numerically...
