Abstract Wire arc additive manufacturing (WAAM) of large component is susceptible to residual stress (RS) and distortion, which are detrimental need be mitigated through high pressure rolling or other methods. In this study, an efficient modelling approach developed simulate both WAAM rolling, can also applied processes determine steady-state variables. For a clamped wall component, the computa...

Abstract The use of wire arc additive manufacturing (WAAM) in conjunction with topology optimisation enables the production structural components significantly higher strength‐to‐weight ratios than conventional components. However, owing to additional stages involved WAAM ( e.g . welding), a common question arises regarding environmental impacts using produce relative fabrication techniques hot...

Wire injury of an artery has been recognized as a standard model of vascular inflammation and atherosclerosis; however, the mechanism of leukocyte recruitment has not been studied in this model. In this study, we documented the recruitment of leukocytes to the murine femoral artery after a wire injury. A transluminal mechanical injury was generated by insertion of a wire into the femoral artery...

A proof of the theorem giving maximum available active power with constant transmission losses (i.e., efficiency) valid for arbitrary waveforms, is proposed. This makes it possible to rigorously generalize definitions factor based on definition apparent as apply them systems non-symmetric, non-sinusoidal, and eventually time-varying non-periodic) waveforms or DC grids, thus extending its applic...

A low carbon steel was processed by Cold Rolling (CR) and Asymmetrical (ASR) at room temperature until 200 μm thickness reduction using multiple rolling passes of 25 μm. ASR process induced a soft curvature with 45.7 mm length 128.8 radius, while the CR did not show any curvature. Materials showed differences in strain path as well texture microstructure evolution, only concerning mode deformat...

The latest development trend in rolling industry is the combination of various technological operations continuous production lines. In long products, and drawing processes looks promising. A wire mill developed by team authors this work belongs to conceptually new, integrated creation new mills requires a research phase, where relevant concepts are scrutinized using methods mathematical modeli...

Coordinated landing requires anticipating the timing and magnitude of impact, which in turn requires sensory input. To better understand how cane toads, well known for coordinated landing, prioritize visual versus vestibular feedback during hopping, we recorded forelimb joint angle patterns and electromyographic data from five animals hopping under two conditions that were designed to force ani...

High pressure multi-layer rolling is an effective method to reduce residual stress and distortion in metallic components built by wire arc additive manufacturing (WAAM). However, the mechanisms of reduction during are not well understood. Conventional finite element models for highly inefficient, hindering simulation large WAAM components. This study aims identify most suitable modelling techni...
