Stress analysis of thin and thick plates on elastic foundations using boundary and finite element methods [PDF]
, 1991 In this work an attempt has been made to derive a full finite element and boundary element theory for the analysis of thin and thick plates on elastic foundations. A new high order shear finite element capable of the analysis of thin thick plates has

Solution of contact problems of anisotropic plates bending on an elastic base using the compensating loads method [PDF]
E3S Web of Conferences, 2023 In critical structures used elements consisting of anisotropic materials with concentrated force or moment applied to them are often found. In order to equalize the internal force factors, as well as to ensure the required strength and rigidity of the ...

Singular perturbation decomposition-based ride quality control of elastic aircraft
Xibei Gongye Daxue Xuebao/Journal of Northwestern Polytechnical University, 2023 Considering the reduction of ride comfort under wind disturbance, the ride quality control method based on singular perturbation decomposition is proposed. For the dynamic model of elastic aircraft, the singular perturbation theory is used to decouple the model into the rigid-slow subsystem and the flexible-fast subsystem.

Bifurcation and singularity analysis of HSLDS vibration isolation system with elastic base [PDF]
Journal of Vibroengineering, 2018 In order to reveal the bifurcation mechanism and optimize the system design for high-static-low-dynamic-stiffness (HSLDS) vibration isolation system (VIS) with elastic base, the local bifurcation analyses both in unfolding parameter space and physical parameter space were carried out theoretically and numerically.

Journal of Marine Science and Engineering, 2023 Marine-vehicle manipulators, which represent a kind of mechanical systems installed on marine surface or underwater vehicles, are mostly suffering from the problem of waves (or ocean currents)-caused base oscillations. The oscillations have a significant
