Dynamic Analysis with Three Beam Theories for a Rotating FGM Micro-Beam Based on Meshless Methods

Applied Sciences
This paper investigates the dynamic characteristics of rotating functionally graded material (FGM) micro-beams based on Euler–Bernoulli beam theory, Euler–Bernoulli beam theory incorporating shear deformation, and Timoshenko theory. The deformation field

Simulation of Locally Varying Residual Strains in 4D Printing

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Shape memory polymers (SMPs) are a class of materials capable of storing deformation in a programmed shape, which can be recovered when an external trigger, such as temperature, a magnetic field, or similar is applied. In the classical shape memory cycle, programming consists of successive heating, deformation and cooling steps. In combination

Timoshenko versus Euler beam theory: Pitfalls of a deterministic approach

, 2011
The selection criteria for Euler-Bernoulli or Timoshenko beam theories are generally given by means of some deterministic rule involving beam dimensions.

Free vibration analysis of angle-ply laminate composite beams by mixed finite element formulation using the Gâteaux differential

Science and Engineering of Composite Materials, 2014
Free vibration analyses of angle-ply laminated composite beams were investigated by the Gâteaux differential method in the present paper. With the use of the Gâteaux differential method, the functionals were obtained and the natural frequencies of the ...

Load Distributing Metamaterials Via Discrete Optimization

Advanced Functional Materials, Volume 36, Issue 82, 12 October 2026.
Mechanical metamaterials are computationally optimized to homogenize transmitted forces by minimizing the spread of reaction forces. The resulting architectures transform localized loading into broader, more uniform force distributions and experimentally demonstrate robust load spreading under quasi‐static and impact loading.

Shear Coefficients for Timoshenko Beam Theory

, 2000
The Timoshenko beam theory includes the effects of shear deformation and rotary inertia on the vibrations of slender beams. The theory contains a shear coefficient which has been the subject of much previous research.

Fine‐tuning ab initio XANES spectra calculations using the Bayesian optimization algorithm

Journal of Synchrotron Radiation, Volume 33, Issue 5, Page 1455-1466, September 2026.
A Bayesian optimization technique is used to tune the FEFF and FDMNES packages and to improve matching between theoretical and experimental spectra. The tests were performed on monometallic Ni, Fe and Pd K‐edge XANES spectra using several different spectrum similarity metrics.Theoretical modeling of X‐ray absorption near‐edge structure (XANES) spectra ...
