Abstract

IN THE PRESENT PAPER, BUCKLING ANALYSIS OF FUNCTIONALLY GRADED RECTANGULAR MICRO-PLATES, ON THE BASIS OF STRAIN GRADIENT THEORY WITH ONE LENGTH SCALE PARAMETER IS STUDIED. CONSIDERING THE KIRCH-HOFF PLATE THEORY AND THE PRINCIPLE OF MINIMUM TOTAL POTENTIAL ENERGY, GOVERNING EQUATIONS OF MICRO-PLATE SUBJECTED TO IN-PLANE LOADS ARE EXTRACTED. IN ACCORDANCE WITH FUNCTIONALLY GRADED DISTRI-BUTION OF MATERIAL PROPERTIES THROUGH THE THICKNESS, HIGHER ORDER GOVERNING EQUATION OF SIXTH ORDER IS DERIVED. CONSEQUENTLY, THE STABILITY EQUATION IS SOLVED ANALYTICALLY FOR SIMPLY SUPPORTED MI-CRO-PLATES AND THE EFFECTS OF MATERIAL PROPERTIES, MICRO-STRUCTURE PARAMETERS, DIMENSIONS AND LOADING CONDITIONS ARE EXPOUNDED ON THE CRITICAL BUCKLING LOAD.
