A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

Advanced Engineering Materials, EarlyView.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

The relationship between toe gripping force and balance ability

, 2011
本研究の目的は、足指把持力とバランス能力との関係性を検討することである. 対象は、健常な中高年女性13名(年齢59.8±4.3歳)と若年女性11名(年齢22.5±1.9歳)とした. 対象者には、足指把持力と立位での足圧中心(COP)の総軌跡長を測定した. COPの総軌跡長の測定は、条件の異なる2つの立位にて実施した. また、足指が床に接地した状態と接地していない状態とでFunctional Reach Test(FRT)を実施した.

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones

Advanced Engineering Materials, EarlyView.
A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

Effect of Oxygen Content on Surface and Subsurface Integrity During Turning of Ti–6Al–4V

Advanced Engineering Materials, EarlyView.
This study examines how oxygen content in the ambient atmosphere affects the surface and subsurface properties of Ti–6Al–4V during turning. Results show that oxygen does not influence surface roughness. However, machining in an extremely high vacuum‐adequate atmosphere increases surface hardness by up to 7.8% and induces compressive residual stresses ...

Altered anconeus muscle activation characteristics during isometric gripping in individuals with lateral elbow tendinopathy compared to age- and sex-matched control

Purpose Individuals with Lateral Epicondyle Tendinopathy (LET) commonly experience gripping deficits, which are marked by pain and altered motor control of the forearm extensors and flexors. Although delayed activation of the anconeus muscle during rapid
