Abstract: A semi-analytical method and a numerical method were used to investigate the vibration characteristics of an axially moving variable length (velocity) beam with a tip mass. First, the equation of transverse free vibration for the axially moving Euler beam was simplified. The eigenequation was derive...
Abstract: For a planar waveguide filled with periodic parallel finite-length carbon nanotube array, we got the dielectric properties of the parallel carbon nanotube array based on the equivalent medium model for parallel carbon nanotube arrays while ignoring the spatial dispersion but considering the electrom...
Abstract: Traditional static influence line was developed into dynamic field, and dynamic influence lines of deflections in the mid span of a simply-supported bridge and a three-span elastically supported bridge were studied by considering the effect of interaction between the bridge, the bridge random surfac...
Abstract: The thermal buckling equation for thin spherical shells was deduced on the basis of axisymmetric thin spherical shell buckling equation derived with the tensor method. The thermal buckling equation involving the coupling of uniform external pressure and temperature was expressed in terms of displace...
Abstract: The thermal bending of the grid sandwich beam was considered to be equivalent to the deformation of the micropolar thermoelastic beam under thermal load, and the control equations of thermal deformation for the equivalent micropolar thermoelastic beam were established based on the plane micropolar t...
Abstract: The anti-plane elasticity problem of the 1D orthorhombic quasicrystal with a semi-infinite crack penetrating along the quasiperiodic direction was investigated through introduction of a new generalized conformal mapping and with the generalized complex variable method. The analytical solutions of th...
Abstract: In the solving of the elastic wave equations with the numerical approximation techniques, the absorbing boundary conditions had been widely used to truncate the infinite-space simulation to a finite-space one. The perfect matched layer (PML) technique as an absorbing boundary condition had exhibited...
Abstract: High-pressure hydraulic fracturing (HF) is an important part of the safety-assessment of high concrete dams. Fluid-structure interaction during the progress is the keypoint to accurately predict crack growth path and risk level. In this paper, the extended finite element method (XFEM) was used for n...
Abstract: Electroosmotic flow is widely used to transport and mix fluids in microfluidic chips. A variable model for the ion concentration gradient effects on the electroosmotic flow and micromixing in microchannels was presented. The effects were investigated numerically with the finite element method. The i...
Abstract: Many researchers have paid attention to the shallow water wave model Camassa-Holm (CH) equation over the last two decades. The one-periodic solution of CH equation based on the Hirota bilinear method had been presented in our previous work. In this paper, we offer quasi-periodic solution in genus tw...
Abstract: A class of nonlinear disturbed generalized NNV (NizhnikNovikovVeselov) system was addressed with a simple and valid technique. Firstly, the soliton solution to the corresponding typical differential system was obtained by means of the undetermined coefficient method. Secondly, a generalized functi...
