Fault detection and isolation (FDI) problem for nonlinear dynamic systems has received more and more attentions recently. The significant results mainly belong to three kinds of methods: The method based on nonlinear geometrical theory (1; 2; 3), based on parity space theory (4; 5) and based on adaptive observers (6; 7). The application of the first one is limited because there is not always su...

In this paper, the nonlinear dynamic buckling of double-walled boron-nitride nanotube (DWBNNT) conveying viscous fluid is investigated based on Eringen's theory. BNNT is modeled as an Euler-Bernoulli beam and is subjected to combine mechanical, electrical and thermal loading. The effect of viscosity on fluid-BNNT interaction is considered based on Navier-Stokes relation. The van der Waals (vdW)...
