Abstract


The aim of the paper is to carry out experimental verifications regarding the elasto-plastic deformation of round, thin-walled pipes. The paper has two goals. The first goal was to create a clamping device for long pipes. The second goal was to carry out specific experiments with this device, which would verify the calculation relation obtained in a previous theoretical research. The paper presents aspects related to the design and manufacture of the device. The experiments carried out are also presented, through which the elasto-plastic deformation that occurs when processing holes in long, thin-walled pipes was highlighted, and compared to the theoretical relation previously established. The conclusions presented confirm the achievement of the proposed goals, through 100% original contribution.
