Three Dimensional Photoplasticity Simulation on Skew Rolling
Using polycarbonate as mold material,three dimensional photoplasticity was employed to simulate the metal deformation in skew rolling process.The fringes of isochromatic line and isoclinal line of slice in typical section was observed and analysed.The 3-D strain distributions in the inner of skew rolling part were solved by Newton iterative method.The results show that the deformation distributions on skew rolling are complicated 3-D deformation,the central deformation is smallest and the ambient deformation become more and more large;the simulation method of 3-D photoplasticity of skew rolling is successful and it provides an effective experiment means for studying metal forming technology.
