About Buckling Bio-Composite Sandwich Bars

Abstract:

Abstract. The bio-composites materials are very important for a lot of industry and life domains, particularly in the aeronautic industries and medicine, in orthopedics. Titanium and its alloys are most widely used, due to their mechanical properties similar to bone tissue. The sandwich structures are very light, they have a high stiffness in flexion and very good thermal characteristics. For the compressed sandwich structures, risks of buckling are higher than the conventional compressed structures, limited by a critical value of the applied force, then the deformations grow in importance and uncontrolled manner. We try to calculate the critical buckling force by the method presented in [2].
