Simulation of Locally Varying Residual Strains in 4D Printing

open access: yesProceedings 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

Thermoelasticity and Irreversible Thermodynamics [PDF]

open access: yesJournal of Applied Physics, 1956
A unified treatment is presented of thermoelasticity by application and further developments of the methods of irreversible thermodynamics. The concept of generalized free energy introduced in a previous publication plays the role of a ``thermoelastic potential'' and is used along with a new definition of the dissipation function in terms of the time ...

Thermo‐Fluid‐Structural Coupling Analysis of Twin‐Screw Compressor Rotors Under Variable Operating Conditions

open access: yesApplied Research, Volume 5, Issue 5, October 2026.
A validated thermo‐fluid‐structural coupling framework reveals that rotor von Mises stress exhibits a non‐monotonic trend with discharge pressure, reaching a minimum at 0.3 MPa (3000 rpm)—identifying a structurally optimal operating point that minimizes mechanical loading and extends fatigue life.

Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 14964-15009, 15 September 2026.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

Performance Enhancement of Thermoelectric Generators Integrated With Phase Change Materials: A Transient Numerical Analysis

open access: yesEnergy Storage, Volume 8, Issue 6, September 2026.
ABSTRACT This study presents a numerical analysis of thermoelectric generators (TEGs) integrated with a heat sink and phase change materials (PCMs), focusing on their combined impact on thermal management and power output. The module, comprising a bismuth telluride (Bi2Te3)‐based TEG coupled with a paraffin wax PCM, was evaluated using finite element ...

A Label‐Free Ultraviolet Photoacoustic Microscopy Enables Nuclear Imaging and Toxicity Assessment in an Intact Brain Organoid

open access: yesSmall, Volume 22, Issue 51, 11 September 2026.
Ultraviolet photoacoustic microscopy enables label‐free visualization of nuclear morphology in intact human brain organoids. By exploiting endogenous nucleic acid absorption at 266 nm, this approach resolves individual nuclei without staining or sectioning.

Decay rate of the solutions to the Cauchy problem of the Lord Shulman thermoelastic Timoshenko model with distributed delay

open access: yesDemonstratio Mathematica
In this study, we address a Cauchy problem within the context of the one-dimensional Timoshenko system, incorporating a distributed delay term. The heat conduction aspect is described by the Lord-Shulman theory.
