Abstract
This study focuses on evaluating the performance of sandwich beams under three-point bending test. Three sandwich beams consisting of transverse cores of Honeycomb, Beta, and Alpha with the same face sheets thickness are fabricated by employing a 3D printer. The extended high order sandwich beam theory has been used to carry out the static analysis of three-point bending behavior of the beams for the first time by this work. In order to compare the theoretical results, numerical simulations were implemented in ABAQUS software and experimental tests were performed. The theoretical results with less than 5% error follow the experimental ones. The tremendous achievements of the current investigation provide a novel insight into prognosticating the performance of the 3D printed sandwich beams.
