| Abstract: | Based on the basic theory of plasticity,through the material stress-strain relationship revealed the root causes of thinning during plate bending.Referring to the theory of wollter,the theoretical formula for calculating the thinning volume was derived.According to the theoretical results,bending experiments for the high-strength aluminum alloy plate used in high-speed train were carried out.Adopting high-precision measuring instruments,data of thinning during bending of different materials under different conditions were obtained..The experimental data is in good agreement with the calculating results.The results have a theoretical value and practical significance for formulating bending technology. |
