Aimed at the partial slip problem of contact interface between assemblies at different temperatures, a semi-analytical model for 3D steady-state thermoelastic partial slip contact was established. Based on the thermoelastic theory and the heat conduction equation, the frequency response functions of...

A numerical method based on the panel method was developed to calculate the added fluid mass coefficients of the rigid section group with arbitrarily complex shapes, and was successfully applied to the PWR fuel assemblies. The variation law of added mass coefficients with position deviations was ana...

The top ends of marine risers are usually hinged under the floating platform, and the vortex-induced vibration due to ocean currents often leads to the potential fatigue damage. The non-intrusive optical measurement (high-speed camera) was employed to monitor the displacements of top-hinged-and-bott...

The adsorption behavior of impurity gases on the surface of alloy ZrCo has an important influence on its hydrogen storage performance. The adsorption behavior of O₂ on the ZrCo(110) surface was investigated with the first principles based on the pseudopotential plane wave method. The results of adso...

A linear buckling model for double-layered microplate systems filled with elastic media between layers was developed under the modified couple stress theory and the 2-variable higher-order shear deformation theory. The governing differential equations for system buckling were derived based on the Eu...

Double-curved-beam (DCB) systems are usually seen in many engineering fields. Compared to straight double-beam systems, DCB systems are more efficient in noise and vibration control problems. To obtain closed-form solutions of steady-state forced vibrations of DCB systems, the classical Euler-Bernou...

The flutter responses of the Nanjing No.4 bridge flat box girder under different wind attack angles were tested in detail through sectional model tests. The evolution of unsteady and steady critical amplitudes at different wind speeds was discussed. Based on the amplitude envelope of the flutter res...

Based on the homotopy analysis method, the nonlinear vibration of porous functionally graded material (FGM) conveying pipes under generalized boundary conditions was studied. Based on the power-law distribution of the FGM and the Voigt model, the physical properties of the porous pipe material were ...

As more and more structural parts of military aircraft are formed with the additive manufacturing (AM) technology, it is very urgent to study the fatigue characteristics of the additive manufactured materials and structures. To investigate the fatigue life characteristics of the aluminum alloy and t...

To study the effects of bamboo fiber and steel wire mesh on the flexural ductility of basalt fiber reinforced polymer（BFRP）bar concrete beams, 7 BFRP bar concrete beams with bamboo fiber and steel wire mesh were tested with different bamboo fiber lengths (0 mm, 30 mm and 45 mm) and different steel w...

The uneven riverbed, and the impact and scour actions by water flow, make the underwater buried pipeline vulnerable to exposure and suspension, and endanger the pipeline operation safety. To investigate the mechanical properties and failure behaviors of the suspended pipeline section under water imp...
