ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 6, June 2026.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
physica status solidi (b), Volume 263, Issue 5, May 2026.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).

MODES OF VIBRATION OF THE BEAMS UNDER THE INFLUENCE OF DISCONTINUITY IN FOUNDATION
Facta Universitatis. Series: Mechanical Engineering, 2014 Vibrations of the Timoshenko beams resting on the Winkler and Pasternak elastic foundation with discontinuity are investigated in this paper. A p-version finite element method that accounts for shear deformation is used.

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 3, March 2026.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 ...

Study on Impact of Foundation Pit Construction on Surrounding Tunnels Considering Its Shear Effect
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.It is necessary to assess the pit construction impact on surrounding tunnels. The improved Hermite interpolation difference scheme is used to derive the solution formula. Then, the rationality and applicability of the Timoshenko deep beam model considering the shield tunnel shear effect are verified by analyzing and comparing with the measured data of ...
