welded flange

Welded flange forming process is very complex, especially for large welded flange production cost is great, often need to warm up beforehand. Computer simulation of deformation of the flange is related to the process of raw materials and deformation temperature and the mechanical properties of a mathematical model representation, by means of computer simulation at any instant during deformation and stress-strain state temperature distribution. Process using computer simulation and physical simulation, the two can be mutually supporting and complementary. As Hydraulic tube fittings forming process and the physical existence of geometric nonlinear nonlinear problems, so that the main stress method, slip line method and the upper bound method and other traditional methods in the analysis of the type of problem and the practical application of aspects there are significant limitations sex. The finite element method so that the physical characteristics of the plastic deformation process to get real inclusion, to comprehensively consider various boundary value, initial conditions, and for complex boundary with high fitting accuracy, thus becoming the metal forming process Numerical Simulation of the mainstream approach
