A general series-type theoretical formulation based on the linearized potential theory, the method of separation of variables, and the translational addition theorem for cylindrical Bessel functions is developed to study three-dimensional natural sloshing in a partially filled horizontally-mounted circular cylindrical tank of finite span. Assuming...

A three-dimensional hydrodynamic analysis founded on the linear water wave theory and separation of variables in elliptical coordinates is undertaken to investigate the free sloshing characteristics in the doubly connected fluid domain of an upright (rigid-walled) cylindrical vessel of elliptical cross section that contains an internal (nonconfocal...

A structural model is provided for the analysis of mechanical responses of folded quadrilateral plates which constitute the building blocks of most Origami/Kirigami inspired structures. This model uses the first order shear deformation theory (FSDT) to account for the elastic deformation of the facets. The behavior of the folds at the intersection...

Mechanical connections such as bolts and rivets are inevitable in most engineering structures and may significantly affect the dynamic behavior of the structures. Therefore, modeling a joint simply and accurately is essential for assembled structures. On the other hand, the most important step is the determination of these joint model parameters wh...

Identification and modeling of joint dynamics is an important issue in the dynamic modeling of structures with joints. Moreover, structures connected by joints may show nonlinear behavior due to the existence of dry friction between the connected elements, especially at higher levels of vibration. Therefore, nonlinear identification of joints and p...

Prediction of the forced response of coupled structures in contact may become computationally expensive due to the nonlinearity in the system. However, the dominant nonlinearity in the coupled structure is localized at the contact interface which gives the opportunity to solve the nonlinear equations only for connection degrees of freedom (DOF) ins...

The aim of this study is to derive and compare the performance of the linear model with its nonlinear version, in oscillation of the gas bubble. Dynamics of a bubble in N-dimensional, viscous domain by considering surface tension effect for the bubble, under harmonic acoustic pressure fields is formulated by N-dimensional nonlinear Rayleigh-Plesset...
