Size effects on free vibration of heterogeneous beams
MATEC Web of Conferences, 2018 In this paper the influence of microstructure on the free vibration of geometrically similar heterogeneous beams with free-free boundary conditions was numerically investigated by detailed finite element analysis (FEA) to identify and quantify any effect

Ecology and Evolution, Volume 15, Issue 12, December 2025.The co‐adaptation of bees from the genus Macropis and Lysimachia plants has been studied in detail. Research shows that bees collect not just pure liquid oil from flower petals but tear off trichome heads filled with oil, transferring them to their nests.

On Stability of Hyperbolic Thermoelastic Reissner-Mindlin-Timoshenko Plates
, 2013 In the present article, we consider a thermoelastic plate of Reissner-Mindlin-Timoshenko type with the hyperbolic heat conduction arising from Cattaneo's law. In the absense of any additional mechanical dissipations, the system is often not even strongly

PAMM, Volume 25, Issue 4, December 2025.ABSTRACT Metamaterials are artificially designed structures that exhibit tailored mechanical properties. These properties result primarily from their underlying small‐scale architecture and can therefore be improved by adapting this structure. In this work, the mechanical behaviour of the two‐dimensional projection of the underlying structure is ...

Peridynamic Solutions for Timoshenko Beams
Engineering, 2014 Peridynamics is a recently developed formulation for continuum mechanics which describes material deformation using a nonlocal approach. Unlike Classical Continuum Mechanics (CCM) where the conservation equations are cast into partial differential equations, Peridynamics describes the deformation in terms of integro-differential equations ...

Weak solutions for a singular beam equation
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 12, December 2025.Abstract This paper deals with a dynamic Gao beam of infinite length subjected to a moving concentrated Dirac mass. Under appropriate regularity assumptions on the initial data, the problem possesses a weak solution which is obtained as the limit of a sequence of solutions of regularized problems.

Sensing and Bio-Sensing Research, 2015 We present a sensor model comprised of a Timoshenko beam coupled with a linear viscoelastic substrate via a distributed system of compliant elements. The system of governing equations includes the evolution of the kinematic descriptors of the Timoshenko ...

Shape optimization of a Timoshenko beam together with an elastic foundation [PDF]
, 2010 In this article we are going first to aim at the variational ormulation of the bending problem for the Timoshenko beam model. Afterwards we will extend this problem to the Timoshenko beam resting on the Winkler foundation, which is firmly connected with
