In many engineering structures such as columns, beams, or plates, their failure develops not only from excessive stresses but also from buckling. Buckling characteristics are used in design of automobile components such as engine connecting rod, push rods etc., when subjected to in plane compressive loads as the evaluation index. There are, however a limited number of studies on the buckling of columns on various engineering materials. The objective of the present study is to fabricate and compare the buckling loads of AL6061/SiC composites containing SiC particulates of (400 mesh) and AL6061/SiC/Graphite containing SiC particulates of (400 mesh) and Graphite(1 Nano) Hybrid particulate composites. The reinforcing particulates in the MMC's vary from 0% to 15% by weight in varying steps of 5%. The composites were tested as per ASTM Standards for mechanical properties and buckling tests were conducted on the computerized UTM with different set of material properties of composites, and the experimental buckling loads are compared with analytical buckling loads using Johnson's parabola equation. The main aim of this work is to increase the buckling stability and to reduce the weight of the column compared to pure metals. © Research India Publications.
