Brittle Creep as a Mechanism for Postseismic Relaxation in Upper Crustal Dolomite Marble
Abstract In many locations, earthquakes in the upper crust occur in carbonate rocks, whose deformation affects aftershock sequences and postseismic relaxation. We investigate the stress relaxation process and strain evolution in Jinping dolomite marble (porosity <0.2%) subjected to multi‐stage stress ramp‐relaxation cycles under confining pressures of ...

ABSTRACT This study investigates the torsional vibration characteristics of double‐walled carbon nanotubes (DWCNTs) considering viscoelastic effects and nonlocal elasticity theory. The equations of motion are formulated based on the nonlocal constitutive relations and viscoelastic material behavior to accurately capture the small‐scale and time ...

Negative Stiffness Induced and Controlled by Constriction
Structures with negative stiffness can be stabilized by constriction of external displacement. Furthermore, constriction can make a conventional positive stiffness material exhibit negative stiffness, either bidirectional or unidirectional (shown in the figure).

Abstract In this study, a comprehensive analytical framework is developed to investigate the free vibration behavior of double‐walled carbon nanotubes (DWCNTs) resting on an elastic foundation, based on Eringen's nonlocal elasticity theory. The DWCNTs are modeled as two coupled Euler–Bernoulli (EB) beams, explicitly incorporating intertube van der ...

A Finite Element Study of the Bending Behavior of Beams Resting on Two-Parameter Elastic Foundation
Although the Winkler’s model is a poor representation of the many practical subgrade or subbase materials, it is widely used in soil-structure problems for almost one and a half century.
