[Problem] To provide a means for forming a thin-film in a desired part of an object to be treated. [Solution] The thin-film formation means according to the present invention is part of a thin-film formation method which supplies electricity to a raw-material gas in a reduced pressure container, converting the raw-material gas to plasma, and irradiates the plasma, thus forming a thin-film on the surface of an object to be treated. Therein, the effect of a magnetic field generated by a magnetic field generating means is used to form the thin-film in a desired part. The effect of the magnetic field focuses the flux of the plasma in a desired part of the surface of the object to be treated, thus enabling the thin-film to be formed in the desired part.

The characteristics of the wire are calculated, the wire having a cross-sectional shape which is substantially uniform along its length and having a length long enough in comparison with a diameter being deformed. The wire is divided into a plurality of elements with predetermined spacing along the length. When the wire is deformed, the shape of the wire after the deformation is determined. In the determined shape, a tangential stiffness equation using the element as a basis is calculated, and the calculated tangential stiffness equation is translated into a tangential stiffness equation using the whole of the wire as a basis. A global stiffness equation representing the whole wire is calculated from the tangential stiffness equation obtained by the translation. A load or a displacement produced in each portion of the wire is calculated from the global stiffness equation and the determined shape of the wire.

Optimum conditions for extrusion forging by using a powder material are determined by making a cylindrical billet out of the powder material, subjecting it to a deformation stress between plates to measure its strain as well as the time-rate of change in the strain, thereby determining parameters in the stress-strain formula, and carrying out a simulation analysis by an arbitrary Lagrangian-Eulerian method with an equation of motion obtained by the principle of virtual power. In considering the virtual power, bulk work is also taken into consideration. By such simulation analysis, data such as pressure distribution, speed distribution and density distribution are obtained. Optimum conditions are obtained by analyzing these data.
