Energy Allocation Explains How Protozoan Phenotypic Traits Change in Response to Temperature and Resource Supply

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
When cultures of the microorganism Tetrahymena pyriformis are transferred to environments with different temperature and resource levels, the phenotypic traits of the microorganisms—including cell size, metabolic rate, and movement speed—change.

Transient analysis of laminated composite plates using NURBS-based isogeometric analysis

open access: yesVietnam Journal of Mechanics, 2014
We further study isogeometric approach for response analysis of laminated composite plates using the higher-order shear deformation theory. The present theory is derived from the classical plate theory (CPT) and the shear stress free surface conditions ...

On the Extension of Mesh‐Distortion‐Insensitive Petrov‐Galerkin Finite Element Formulations to Linear Elastodynamics

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACT Numerous mesh‐distortion‐insensitive Petrov‐Galerkin finite element formulations have been developed for the simulation of elastostatic problems. This contribution presents initial results on how these formulations can be extended to linear elastodynamics. In this context, three different approaches are examined, building upon an established 8‐

A Quasicontinuum Method With Optimized Local Maximum‐Entropy Interpolation and Heaviside Enrichment for Heterogeneous Lattices

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACTLattice systems are indispensable for modeling and analyzing physical phenomena in materials with discrete or heterogeneous micro‐ or meso‐structures. However, the computational requirements for practical engineering applications of lattice systems remain high.

Numerical Anisotropy and Band‐Gap Formation in Finite Element Wave Propagation: Analysis and Mitigation Using Spline‐Based Elements

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACT Numerical anisotropy and dispersion are inherent consequences of spatial discretization in finite element modeling of wave propagation. In two‐dimensional problems, these effects manifest not only as direction‐dependent phase and group velocities but also as angularly dependent numerical band gaps that may entirely suppress wave propagation ...

Thermal Buckling Analysis of Laminated Composite Plates using Isogeometric Analysis

open access: yes, 2022
Data transmission back and forth between finite element analysis (FEA) and computer-aided design (CAD) is a matter of huge concern today and Isogeometric analysis  has been successful in merging these two fields in the recent past.
