Analysis of Sandwich Corrugated Construction Behaviour at Linear Law of Pressure Supply

Abstract

There was considered regime of forming for sandwich construction from titanium alloy that represents corrugated filling, inserted between two shell plates, by means of linear law of neutral gas supply. This gas entered in the area between filling and shells. There was offered simple model of process, based on the use of torque-free shell theory. There was offered numerical procedure of the main parameters of examined process. There was offered example of special calculation for titanium alloy VT6 (Ti–6Al–4V). The results of calculations on approximate formulae are correspond to numerical solution of boundary problem of recovery creep theory, obtained by means of software ANSYS.
