1+ hour, 3+ min ago   (409+ words) Wall thinning caused by corrosion changes the circumferential strain response of storage tanks, but nonlinear coupling among structural parameters, loading conditions, strain characteristics, and defect geometry makes direct inversion difficult. This paper develops a strain-based, finite element (FE)-based machine…...

5+ hour, 28+ min ago   (421+ words) Proton-exchange membrane fuel cell degradation is one of the factors that limit the deployment of this technology in the automotive market. Accelerated Stress Tests (ASTs) are the standard tool for assessing durability during design and development phases, thanks to their…...

1+ day, 4+ hour ago   (526+ words) This study provides a computational and experimental assessment of the parametric reliability of friction pairs in brake devices for lifting and transport technology. The computational and experimental method for assessing the parametric reliability of various friction units in lifting and…...

1+ day, 5+ hour ago   (502+ words) Partial discharge (PD) generates transient acoustic-vibration signals that can be used for the passive monitoring of cable insulation. Unlike previous studies that separately addressed DFB-FL sensitivity, polymer-property effects, or acoustic attenuation in a particular cable, this study establishes an application-oriented…...

1+ day, 6+ hour ago   (506+ words) This study presents SenseMat, a modular sensing infrastructure based on recycled end-of-life tire (ELT)-derived rubber flooring that integrates continuous body-weight (BW) estimation, environmental monitoring and Internet-of-Things (IoT) connectivity into a single structural livestock infrastructure. Designed as a modular engineering…...

3+ day, 8+ min ago   (468+ words) The rubber cylinder is the core sealing element of a compression packer, and its structural stability directly determines downhole sealing reliability. The rubber cylinder is made of HNBR, while the central tube, support rings, and casing are made of 35 CrMo…...

3+ day, 1+ hour ago   (459+ words) Electrostatic discharge (ESD) in fluoropolymer-lined Standard Clean-1 (SC-1) delivery systems is a reliability concern in semiconductor wet processing, yet its physicochemical pathway remains uncertain. This field-based study investigated ESD-damaged perfluoroalkoxy alkane (PFA)- and polytetrafluoroethylene (PTFE)-lined components using operational observations,…...

3+ day, 3+ hour ago   (329+ words) Annular fillet welds on guide rods lie in stress concentration zones and are susceptible to fatigue failure under dynamic suspension loads, necessitating accurate quality inspection. However, their complex three-dimensional topography makes it difficult for conventional methods to balance detection accuracy…...

3+ day, 5+ hour ago   (525+ words) Seismic pier-top pounding in high-speed railway bridges transfers short-duration girder-restraint contact forces into bridge piers, coupling local contact damage with global vibration and possible base yielding. This critical review evaluates how evidence and modelling strategies can be transferred from local…...

3+ day, 7+ hour ago   (248+ words) This study examined the reported splitting-tensile response of 17 concrete mixtures labeled by nominal rubber replacement levels of 5–20% and steel fibers at 0–1.5% by volume after 7 and 28 days of curing. The reported strength values were considered together with failure photographs, representative load-displacement…...
