“…Superplasticity is a characteristic of some fine-grained (3-5 lm) alloys when specimens under low stress conditions can exhibit neck-free elongations of very large values [39,40]. Since the first superplastic part was made pneumatically from a sheet of superplastic Al-Zn eutectoid alloy 50 years ago [41] (see in Figure 23), this technology has been actively pursued in academic, research organizations and industrial R&D facilities around the world due to its special advantages of meeting some unique requirements in the aerospace and automobile industry.…”

-Lightweight materials, such as ultra-high strength steel, titanium alloys and aluminum alloys, are used widely in aerospace and automobile industries leading to increasing demands for advanced forming technologies. Recently many innovative sheet-and tube-forming methods have been proposed by researchers and R&D facilities around the word. These methods can greatly improve the formability of materials with low plasticity and can produce complex-shaped parts with good surface qualities. This review aims at providing an insight into the latest developments of particular sheet-or tubular-metal forming process and shows basic applications in modern industry.

“…Кроме того, освоена техноло-гия изготовления из того же сплава и по той же техноло-гической схеме сферических сосудов высокого давления для крылатых ракет среднего радиуса действия, а также коррозионно-стойких поплавков контакторов уровня жидкости для химической промышленности. Посколь-ку изделия аналогичного назначения производятся не только на Тайване, имеется множество публикаций, посвященных анализу напряженно-деформированно-го состояния и расчету основных технологических па-раметров процесса СПФ листового проката в матрицу цилиндрической формы, см, например, [27][28][29][30][31][32][33][34][35][36][37]. Каждый год появляются все новые и новые публикации, в работу вовлечены исследователи США, Японии, России, Индии, Китая, Кореи, Тайваня, Сингапура и других стран.…”

“…Some problems in ÿnite element analysis may not be readily solved by implicit methods of solution such as contact between corner and curved concave surface [1][2][3]. In such cases, where a sharp-pointed edge contacts a concave surface, explicit (EXP) or direct integration of momentum equations is an alternative scheme of solution.…”

SUMMARYAn algorithm combining the numerical execution in time of implicit and explicit methods of solution is presented in this paper. The algorithm swaps between both methods as required for the analysis. The whole mesh is solved for an unique method at once, i.e. there are no partitions of the mesh for separate implicit or explicit treatment of the solution. The combination is in-time, in such a manner that if the implicit method starts diverging the explicit one is initiated by appropriate conditions of transition. The formulation is presented ÿrst and its implementation is validated by the analysis of a key numerical example.
