2중 원형관의 2축압축 변형특성에 관한 연구

The deformation characteristics of double round copper pipe and single round copper pipe under biaxial compression were studied using a horizontal compression die. The change of punch load and deformation behavior were monitored in experiments using various compressive deformation rates in the range 10mm/min. ~ 450mm/min. The punch load decreased with increasing compressive deformation rate. The results of numerical simulations using Deform-2D were in good agreement with experimental results.
