Study on the Compressing and Shearing Deformation with Fringe Technique

Asymmetric rolling is a new method of plasticworking. Recently it is one of obvious features that the subject is made study of by a device (the chief about mechanics) with compressing and shearing deformation. From the viewpoint of stressing main factors and of simplifying the process, it is necessary and significant to use this device.But, with respect to the deformation features of sample on above device and the significancy of above compressing and shearing device for studying asymmetric rolling, it has rarely been considered.
This paper shows the results of the compressing and shearing deformation with the Fringe technique and Spline function smoothing the experimental data.
Experiment was made on compressing and shearing device simulating asymmetric rolling designed by ourselves.It is proved that analysing the deformation under the compressing and shearing state has important significance of theory and practice for revealing the nature of asymmetric rolling and choosing the appropriate type of plasticworking.
