Features of the Process of Stretch Forming Shells Convex-Concave Shape

Abstract:

It is proposed to use actual computer software systems, providing a visualization and automation of the wrinkling and visualization and automation of the results of the numerical finite-element modeling of stretch forming a convex-concave shape in view of the fact that the saddle-backed surface of the shell has two families of asymptotic real straight lines. Along these lines, the saddle-backed surface of the shell with convex-concave shape is easy to break up or riffles are formed along them. The objectives of computer simulation are to predict unwanted distortion geometric form of the shell because of wrinkling and to find a ways to minimize the deviations of its surface deviations from the required shape.
