| Abstract: | Separating the resinic columns from the foam in the core layer,this paper builds a physical model for the elasticity analysis of grooved perforation sandwich beams by use of the commercial finite element software ANSYS.The effects of distribution and material properties of resinic columns on the stress distributions between the core layer and the facial layers are studied,the maximum displacement at the middle of the beam is investigated.The role of resinic columns in preventing delaminations between the co... |
