Theelastic contact deformation between work roll and work-piece, work-piece deformation near the edge of plate and elastic recovery are discussed.

This Paper gives a method of drawing the influence line of fixed end beam and the influence area of fixed edge flat plate which are lying on the elastic foundation bed.

The structure plate is composed of high-elastic structure, which is provided with an edge raised line, a middle raised line, a bottom flat surface and a bottom concave surface.
