Development of computer simulation of industrial superplastic sheet forming

A new technique estimating progressive shape changes for three-dimensional shells based on the generalized cross-sections method is introduced. The formulation of mathematical simulation of technological conditions of forming of three-dimensional shells in conditions of superplasticity is reviewed. An original algorithm of a solution finite element method with usage of orthogonal sections results. The veracity of a receivable solution is analyzed. Experimental tests are realized and a procedure to correlate the idealized forecasts with experimental data is constructed. The results and designed algorithms allow essentially to increase performance and operationability at mining new and retrofit of existing manufacturing processes of gaseous forming in conditions of superplasticity.
