Dynamic buckling and wave propagation analysis of double walled carbon nanotubes based on nonlocal beam and cylindrical shell theories Reza Hosseini Ara r hosseiniara@me iut ac ir Department of Mechanical Engineering Date of Submission Isfahan University of Technology Isfahan Iran Dr Hassan Khademyzadeh supervisor hkhademyza@cc iut ac ir Dr Hamid Reza Mirdamadi supervisor hrmirdamadi@cc iut ac ir Dr Mohammad Mehdi Saadatpour advisor mmehdi@cc iut ac ir Dr Mohamadreza Salimpour Department Graduate program Coordinator Abstract In this research we study the effects of small scale parameter on the static buckling of carbon nanotubes based on a proposed model using nonlocal theory energy principles variational methods and strain gradient approach Based on this model we derive all classical and nonlocal boundary conditions as well as governing equations Therefore closed form and exact critical buckling loads of nanobeams with various end conditions are investigated Moreover we study the effects of small scales Pasternak elastic medium thermal loading and rotary inertia on dynamic buckling of single and double walled carbon nanotubes based on nonlocal Euler Bernoulli and Timoshenko beams and Donnell shell models In addition we study nonlinear dynamic pulse buckling of double walled carbon nanotubes under impact loads Further wave propagation analysis of carbon nanotubes are investigated using nonlocal elastic beam and shell models in order to determine the effects of small scales axial compressive loads Pasternak elastic medium thermal loading rotary inertia and van der Waals forces on single and double walled carbon nanotubes Finally for validating these numerical results they are compared with numerical and MD results in the literature and found to be in good agreement with them These findings are useful in manufacturing the nano sensors for detecting pathogens in a bio medium Keywords Carbon nanotubes Dynamic buckling Wave propagation Nonlocal theory Department of Mechanical Engineering Isfahan University of Technology Isfahan Iran Department of Civil Engineering Isfahan University of Technology Isfahan Iran PDF created with pdfFactory trial version www pdffactory com
