Optimization of the Initial Post‐Buckling Response of Trusses and Frames by an Asymptotic Approach

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 14, 30 July 2025.
ABSTRACT Asymptotic post‐buckling theory is applied to sizing and topology optimization of trusses and frames, exploring its potential and current computational difficulties. We show that the designs' post‐buckling response can be controlled by including the lowest two asymptotic coefficients, representing the initial post‐buckling slope and curvature,

The tensor product of Hopf algebras

open access: yes, 1992
Let \(\mathcal H\) be the category of commutative and cocommutative Hopf algebras over a given field \(K\), and let \(\mathcal C\) be the category of cocommutative, coassociative and counitary \(K\)-coalgebras. An internal Hom in the category \(\mathcal H\), which is a \(\mathcal C\)-valued functor \({\mathcal H} (-, -)\), is defined by associating to ...

The Frequency‐Domain Lattice Boltzmann Method (FreqD‐LBM): A Versatile Tool to Predict the QCM Response Induced by Structured Samples

open access: yesAdvanced Theory and Simulations, Volume 8, Issue 7, July 2025.
FreqD‐LBM simulates the oscillatory flow at the surface of a QCM‐D resonator in the presence of structured adsorbates. It derives shifts of frequency and bandwidth (equivalent to dissipation) on different overtones. Applications include rough surfaces, adsorbed rigid particles, adsorbed viscoelastic particles, spheres floating freely above the surface,
