WebThe elastic cylindrical shell theory has been adopted to study the buckling MWCNTs. An MWCNT consists of two or more single CNTs of radius Ri, thickness h, and modulus of elasticity E. The considered MWCNT is empty inside. No internal or external lateral pressures are applied to the tube except for the pressure caused by vdW interaction. WebThe Method of Cylindrical Shells Again, we are working with a solid of revolution. As before, we define a region R,R,bounded above by the graph of a function y=f(x),y=f(x),below by the x-axis,x-axis,and on the left and right by the lines x=ax=aand x=b,x=b,respectively, as shown in Figure 2.25(a).
