FULLERING OF CYLINDRICAL SAMPLES
The fullering of cylindrical samples by flat, combined dies and dies of a new design studied in the work. Research has been developed using DEFORM-3D software. The strain-stress state of sample during fullering with one rate. Hydrostatic pressure distribution during the deformation of cylindrical samples with use flat and combined dies is heterogeneous in nature. Use new dies promotes uniform of strain-stress state. This completely eliminates the tensile stresses in the central areas of sample. Span values of strain effective decreased by 15 % compared with the combined dies.
