Mechanical behavior analysis of micro structures it is very important to determine their behavioral characteristic and their potential applications. Thetefore, the mechanical behavoire of micro structures has been the subject of many recent studies of the research community. Because micro scale controlled experiments are very difficult and costly using of modified couple stress theory to investigation and prediction of material behaviore on a small scale, it has received much attention in the last decade. In this thesis buckling and postbucking behavior of micro plates based on modified couple stress theory and Keywords: Buckling, Post-bockling, Micro Plate, Modified Couple Stress Theory
