Method of measurement parameters in metal forming.

This master’s thesis deals with the problem of measurement for thermomechanical parameters during metal forming under higher deformation rate. The first part works up general literary studies, comprising a summary of measurement methods for required parameters. There is described a principle of their function and usage. Further assessed the current situation and recommendation of appropriate methods for the dynamic processes of forming, especially their testing. The second part is devoted to the measurement for dynamic features of the material. This is a problem specified by Split Hopkinson preassure bar test. The test is described, including the mathematical evaluation process, in the theoretical part. In the practical part, there is a detailed description of the process and evaluation of the real test with aluminum alloy AlMg4, 5Mn ,07-EN AW 5083 performed within the framework of the junior project
