Numerical investigation and design recommendation for thin-walled octagonal concrete filled steel tubes

open access: yes, 2023
With the growing applications of high strength steel in modern constructions, thin-walled steel tubes attract many attentions. Local buckling failure is the most typical failure mode in a thin-walled steel tube, and concrete filled steel tubes (CFSTs ...

Extrusion‐Based Bioprinting of Living Bioinks for Tissue and Organ Engineering

open access: yesAdvanced Materials Technologies, EarlyView.
Extrusion‐based bioprinting is presented as the most versatile route for fabricating living, heterogeneous tissues. Its ability to combine diverse bioinks, support matrices, and advanced printhead geometries transforms familiar constraints into powerful biofabrication opportunities.

Improving Accident Tolerance of Nuclear Fuel with Coated Mo-alloy Cladding

open access: yesNuclear Engineering and Technology, 2016
In severe loss of coolant accidents (LOCA), similar to those experienced at Fukushima Daiichi and Three Mile Island Unit 1, the zirconium alloy fuel cladding materials are rapidly heated due to nuclear decay heating and rapid exothermic oxidation of ...

On Finite Deformations of Spatially Curved Bisymmetric Thin-Walled Rods

open access: yesArchives of Civil Engineering, 2016
Abstract Deriving the formulas for strain components, we are assuming, that cross-section of a rod being rotated in space during deformation does not need to be perpendicular to deformed centroid line. This not a quite intuitive assumption allows for more compact and easier formulas for strain tensor or equilibrium equations.

From Rigid to Soft Robotic Approaches for Neuroendoscopy

open access: yesAdvanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify

Przyspieszenia Drgań Skrętnych Cienkościennego Pręta o Profilu Otwartym

open access: yesEngineering Transactions, 1970
In this paper is given an approximate method of solving the equations of twisting vibration in a thin-walled rod having one plane of symmetry and with a short-term action of a determined torque on one of its ends.
