The possibility of manufacturing any torso product without creases and tears from a thin sheet made of plastic materials is theoretically proved.
In 1995 on the ХХХI Scientific Conference of the Faculty of Physic-and-Mathematic-and-Natural Sciences of the RUDN University, S.N.
It should be noted that parabolic bending with conservation of rectilinear generatrixes of torso products will be only under the condition of movement of two opposite contour straight edges along the trajectories calculated beforehand and that can be done with the help of the materials of a monography [13, p. 180].

Only materials upon U channel could deform freely.
On the contrary, most materials did not contact with tool surface in tool B at the beginning.
Most of materials could deform freely.
First, bigger width makes much more materials take part in preforming in cavity B than in cavity A.

On the other hand, transportation itself is an important component of domestic economy, and one of the most significant material production departments [3].
On the one hand, environment has provided with indispensable material support and resource security for the operation of the transportation system and fostered the growth and development of it.

METHODS 2.1 Materials The device used in the paper is inverted confocal micro Raman spectrometer (JY LabRam INV) with argon laser, which is produced by Horiba JY Company, and the excitation wavelength is 514.5 nm.
However, using the standard sample for the test of stability and confocal characteristic can ensure the intensity of different spectral can be comparable, which can also make Raman spectroscopy has good correspondence to the material and components of different position.

Concrete choose element of solid65,in order to easily extract the reinforcement stress data, we use separate modeling, and reinforced choose link8 element; The unit of shell41 can be under tensile stress, while not under compressive stress, we choose it realize the better simulation about Carbon fiber, Material parameters of steel and concrete are conventional value obtained from engineering design practice; The mass density of carbon fiber is 1700 kg/m3, the ultimate tensile strength is 3000 Mpa, and modulus of elasticity is 2.3x105 Mpa.
Poisson's ratio of all materials is 0.3.
