Abstracts:

Computer simulation of the rigid-plastic cylinder compression by the flat dies is presented using plane strain ideal plastic theory. Initial contact plastic deformation with material lip forming on the free cylinder surface, followed by the high workpiece and the plastic layer with finite contact length to thickness relation plastic deformation are considered. Prandtl’s slip lines and velocity fields are used for the cylinder section form predictions and plastic layer compression with contact friction consideration. Computer simulation can be used for the limit load estimation with cylinder contact plastic flow, compressed by the flat rigid dies, and cylinder workpiece forging by the flat dies.
