     Problems of high-performance computer simulation and refining the technological regimes of forming airframe panels and calculation of their parts are considered. Some numerical results of using FEM-computations obtained on the MVS-1000 supercomputer and on a cluster of standard PCs are given. An algorithm designed for stress calculation with consideration of the material heteroresistance is applied. Simulation data are compared with small-scale and full-scale experiments. Computing efficiency of clusters with various number of nodes is estimated.
