An Efficient Geometrically‐Exact Nonlinear Shell Formulation Based on Rodrigues Parameters
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT Thin‐walled structures are part of many engineering applications, as wind turbine blades, pressure vessels, and sheet metal products. A thin‐walled structure is characterized by one significantly smaller dimension compared to the others.

Comparative Spectral Analysis of Flexible Structure Models: the Euler-Bernoulli Beam model, the Rayleigh Beam model, and the Timoshenko Beam Model [PDF]
, 2017 We derive herein approximate spectra for three dierent models of transversely vibrating, beams. Each model consists of a system of partial dierential equations (PDEs) with various, boundary conditions.

International Journal of Ceramic Engineering &Science, Volume 8, Issue 2, March 2026.The study reviews existing formulas for the Brittle Ring test and introduces an adapted equation that most accurately determines the fracture strength of ceramic rings. Valid strength values can be obtained with minimal sample preparation when suitable geometric ratios are maintained, demonstrating the method's efficiency for technical ceramics ...

Variational Formulation of Curved Beams in Global Coordinates
, 2013 In this paper we derive a variational formulation for a linear curved beam which is natively expressed in global Cartesian coordinates. During derivation the beam midline is assumed to be implicitly described by a vector distance function which ...

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 ...

ChemElectroChem, Volume 13, Issue 3, 3 February 2026.In pulsed CO2 electroreduction, the electrolyte cation identity and size determine the multicarbon product formation over oxide‐derived Cu nanocatalysts. In situ X‐ray studies revealed enhanced dissolution and increased Cu lattice parameter adaptation linked to enhanced ethanol and suppressed hydrogen formation, suggesting an increased dynamicity of ...
