Stability of Timoshenko systems with past history
Journal of Mathematical Analysis and Applications, 2008 The paper deals with linear one-dimensional integro-differential vibrating systems of the Timoshenko type with past history acting only in one equation. The authors show that the dissipation given by the history term is strong enough to produce the exponential stability of the considered systems if and only if the equations have the same wave speeds ...

Seismic analysis and design of tunnels within fault ground: A review
Deep Underground Science and Engineering, EarlyView.The research methods of seismic response of tunnels within fault ground, including field investigations, analytical solutions, physical experiments, and numerical simulations, and seismic countermeasures are discussed. The present study examines the shortcomings and limitations of the current research and design, and puts forward proposals for future ...

MathematicsThis paper presents a new perspective on the energy decay of a nonlocal truncated Timoshenko–Ehrenfest system. By using the non local elasticity theory, this model is a generalization of the standard truncated Timoshenko system. The well-posedness of the

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT The rotor system of an electrically assisted turbocharger (EAT) is composed of multiple shaft components; The nonlinear connection and contact effects make it difficult to determine the system dynamic characteristics. To improve the modeling accuracy of EAT rotor system and evaluate the influence of contact between multi‐axis components and ...

Structural Concrete, EarlyView.Abstract Grouted sleeve connectors (GSCs) are widely used in precast/prefabricated concrete structures. To ensure force transfer, connectors are often overdesigned in length. This practice has an unintended consequence of reducing the plastic deformation capacity of the connection region and hence the displacement ductility of the precast structure as ...

Structural Concrete, EarlyView.Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.
