AbstractIN THIS STUDY, STATIC ANALYSIS OF THE TWO-DIMENSIONAL RECTANGULAR NANOPLATES ARE INVESTIGATED BY THE DIFFERENTIAL QUADRATURE METHOD (DQM). NUMERICAL SOLUTION PROCEDURES ARE PROPOSED FOR DEFLECTION OF AN EMBEDDED NANOPLATE UNDER DISTRIBUTED NANOPARTICLES BASED ON THE DQM WITHIN THE FRAMEWORK OF KIRCHHOFF AND MINDLIN PLATE THEORIES. THE GOVERNING EQUATIONS AND THE RELATED BOUNDARY CONDITIONS ARE DERIVED BY USING NONLOCAL ELASTICITY THEORY. THE DIFFERENCE BETWEEN THE TWO MODELS IS DISCUSSED AND BENDING PROPERTIES OF THE NANOPLATE ARE ILLUSTRATED. CONSEQUENTLY, THE DQM HAS BEEN SUCCESSFULLY APPLIED TO ANALYZE NANOPLATES WITH DISCONTINUOUS LOADING AND VARIOUS BOUNDARY CONDITIONS FOR SOLVING KIRCHHOFF AND MINDLIN PLATES WITH SMALL-SCALE EFFECT, WHICH ARE NOT SOLVABLE DIRECTLY. THE RESULTS SHOW THAT THE ABOVE MENTIONED EFFECTS PLAY AN IMPORTANT ROLE ON THE STATIC BEHAVIOR OF THE NANOPLATES.
