摘要: TO INVESTIGATE THE THERMAL BUCKLING OF CURVED CARBON NANOTUBES (CCNTS) EMBEDDED IN AN ELASTIC MEDIUM, NONLOCAL ELASTICITY THEORY IS EMPLOYED COMBINATION WITH THIN BEAMS. DIFFERENTIAL QUADRATURE (DQ) METHOD IMPLEMENTED DISCRETIZE RESULTED GOVERNING EQUATIONS. SOLVING THESE EQUATIONS ENABLE US ESTIMATE CRITICAL TEMPERATURE AND AXIAL LOAD FOR CCNTS SURROUNDED BY MEDIUM UNDER EFFECT A UNIFORM CHANGE. INTERACTION BETWEEN NANOTUBE ITS SURROUNDING MODELED AS WINKLERÂPASTERNAK FOUNDATION. FAST CONVERGENCE DQ DEMONSTRATED ALSO ACCURACY VERIFIED COMPARING RESULTS AVAILABLE SOLUTIONS LITERATURE. EFFECTS VARIOUS PARAMETERS SUCH DIFFERENT BOUNDARY CONDITIONS, PARAMETER, WINKLER PASTERNAK MODULUS, CURVATURE ON ARE SUCCESSFULLY STUDIED. REVEAL THAT DEPENDS SIGNIFICANTLY CCNT.
