Vibration of roller chain drives with and without a tensioner.

open access: yes, 1993
A dynamic model based on the axially moving material model is developed to study vibration in roller chain drives without a tensioner. A unique feature of the work presented in this study is that impact, polygonal action and external periodic load have ...

A Dislocation Perspective on Strength and Toughness in Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

open access: yesAdvanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Upper ball joint force variations due to riser tensioner and vessel motions

open access: yes, 1983
Typescript (photocopy).An analysis of the variation of forces acting on the upper ball joint of a riser string due to drill ship motion and riser tensioner dynamics has been conducted. The analysis includes the effect of breakaway torque on the tensioner

Experimental Characterization of Mycelium‐Based Composites Under Multiple Loading Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines the mechanical response of mycelium‐based composites under compression, shear, and tension using mechanical testing and imaging methods. The comparison between unpressed and hot‐pressed specimens shows that hot pressing is associated with higher compression and shear stiffnesses.

The Optimization of a Subsea Pipeline Installation Configuration Using a Genetic Algorithm

open access: yesJournal of Marine Science and Engineering
The most commonly used subsea pipeline installation method is the S-Lay method. A very important and complex task in an S-Lay installation engineering analysis is to find the optimal pipelay vessel installation configuration for every distinctive ...

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

open access: yesAdvanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Condition monitoring of the cam chain tensioner in the motorcycle engine [PDF]

open access: yes, 2014
Timing gear systems of motorcycle engines are equipped with chain tensioners, which are subject to premature damage in certain engine models. Early detection of such damage is essential, as it may protect the user from unexpected engine failure while the
