Abstract This paper presents a probe-based force-controlled nanoindentation method to fabricate ordered micro/nanostructures. Both the experimental and finite element simulation approaches are employed to investigate the...

Concrete-filled steel tubular (CFST) truss arch bridges are widely used in long-span bridge construction due to their high strength, good stiffness, and excellent durability. However, arch rib joints, as critical load-be...

This work introduces a novel geometrical and analytical modeling framework for predicting the stiffness properties of knitted composites, a class of materials known for their complex architectures and versatile mechanica...

Designing floating wind turbine systems requires integrated load assessments (ILA) using fully coupled hydro-servo-aero-elastic models. In most cases, floater hydrodynamics are represented using potential-flow models for...

Abstract Shell-infill structures comprise an exterior solid shell and an interior lattice infill, whose closed features yield superior comprehensive mechanical performance and light weight. Additive manufacturing (AM) ca...

In this paper, we present the development of a rigid-flexible multibody model which, coupled with an existing aerodynamic model, is used to numerically simulate the non-linear aeroelastic behavior of large horizontal-axi...

"Currently, simulations of the induced currents in the brain produced by transcranial magnetic stimulation (TMS) are used to elucidate the regions reached by stimuli. However, models commonly found in the literature are ...

Objective and MethodTo achieve rapid coalbed methane (CBM) extraction from broken-soft coal seams using surface horizontal wells, this study proposed a volume fracturing technology for coal seam roof using horizontal wel...

Abstract Bearing layers are commonly produced using coarse aggregates, gravel, and filler, where excessive filler content can reduce drainage performance. This study investigates an alternative production method for conv...

In this paper, a near-field integrated sensing and communication (ISAC) using a multi-waveguide pinching antenna system (PASS) is proposed, where discrete radiating particles are flexibly clamped along multiple dielectri...

This study aims to continuously optimize the exhaust manifold to ensure long-term stability of reliable performance, and focused on exhaust manifold examining low and high cycle fatigue at high temperatures. The thermal ...

Considering the heterogeneity characteristics of concrete materials, the method of the mesoscopic mechanics is used to investigate the dynamic damage of slabs of concrete face rockfill dam (CFRD) combined with the statis...

The inherent variability of soil properties has currently received considerable attention in slope reliability analysis. However, the geological uncertainty is often ignored in analysis. This paper proposes a method for ...

The structural properties of single component fluids of hard hyperspheres in odd space dimensionalities d are studied with an analytical approximation method that generalizes the rational function approximation earlier i...

Abstract To study the differences in insulation effects of foam box with ice packaging in the aircraft cargo hold environment and the normal pressure environment, and to understand the changes in refrigeration performanc...

"A wide availability of in field Oil & Gas facilities which still have a marginal productive life can be a good opportunity to produce geothermal energy. The challenge is to make good decisions about the company’s asse...

In this new edition of their classic work on Cellular Solids, the authors have brought the book completely up to date, including new work on processing of metallic and ceramic foams and on the mechanical, electrical and ...

En este trabajo de tesis se desarrollan algoritmos de computadora que permiten analizar y diseñar antenas de microtira de forma arbitraria.Para ello, se emplea el método de los elementos finitos, el de los elementos de...

En esta tesis investigamos la clase de los qM3 retículos y la de los mM3−retículos o M3−retículos monádicos, que son M3−retículos dotados de un cuantificador existencial, en el primer caso, y en el segundo d...
