A sandwich structure is designed with dimensions and properties af the faces and core materials given below. 4Asume poon maneras isotropic) a) (2pts) What is the volume fraction occupied by Iaces? b) (2pts) Estimate the densty. c) (3pts) Estimate the Young's Modulus that is loaded in bending as shown in figure below Fipure Q6e Lasding on the componert. d) (9pts) Estimate the strength of the structure that is loaded in bending as shown in figure above. What is the falure mechanism? (Assume tace thickness is high enough to avoid indentation) e) (Spts) On the graph below mark the posiciont of face, core materiais and the sandwich structure. Compare the sandeich with the tace and core materials if material index is o ajp
