Deformation and Energy Absorption of 3D Printed Curved Panels

In this paper an experimental study on the deformation and energy absorption capability of two different curved panels is presented. One of the panels have circular profile, whilst the other, consist of a profile obtained from a third order polynomial line. The results are very sensitive to exact shape and slop of the panels, therefore the specimens were printed with a three dimensional (3D) printer. 3D printing is a fast, simple and precise technique to fabricate complicated objects directly from digital computer aided design files. The results show that polynomial panels have higher peak load and absorbed more energy than circular panels. Also polynomial panels have good integrity and do not break even at the end of loading process
