Shear loaded friction-welded crosswise arranged timber boards

Yves Weinand, Till Vallée, Benjamin Hahn

Friction welding of wood is a bonding technology that can be used for joining timber elements, and in which the adhesive is formed from thermally modified cell wall material within the substrate during the welding process. In this paper, this principle is ...

Stability of extended beam-to-girder shear tab connections under gravity induced shear force

Dimitrios Lignos

Extended shear tab connections are widely used to connect beams to the webs of girders. In the full-depth configuration of extended beam-to-girder shear tabs, the shear plate is typically fillet welded to the web, as well as to the top and bottom flanges o ...

Robotic Assistance by Impedance Compensation for Hand Movements While Manual Welding

Aude Billard, Mustafa Suphi Erden

In this paper, we present a robotic assistance scheme which allows for impedance compensation with stiffness, damping, and mass parameters for hand manipulation tasks and we apply it to manual welding. The impedance compensation does not assume a preprogra ...

New parametric equations to estimate notch stress concentration factors at butt welded joints modeling the weld profile with splines

Anton Schleiss, Pedro Filipe De Almeida Manso, Alexandre Jean Pachoud

For fatigue life estimation as well as for fatigue testing analysis of welded structures by local stresses approaches, the stress concentration factor (SCF) at the weld must be known. Full penetration butt welded joints are extensively used in steel struct ...

Proposed modeling approach of welding procedures for heavy steel plates

Dimitrios Lignos

A numerical modeling approach is proposed to assess the effectiveness of automatic submerged arc welding procedures for steel plates with thickness larger than 50 mm. The scope of study includes partial joint penetration butt welds, their numerical analysi ...

Boosting Water Oxidation Layer-by-Layer

Hubert Girault, Manuel Alejandro Méndez Agudelo, Heron Vrubel, Micheal Diarmaid Scanlon, Véronique Amstutz, Jonnathan Cesar Hidalgo Acosta

Electrocatalysis of water oxidation was achieved using fluorinated tin oxide (FTO) electrodes modified with layer-by-layer deposited films consisting of bilayers of negatively charged citrate-stabilized IrO2 NPs and positively charged poly(diallyldimethyla ...

Anchor Losses Dependence on Electrode Material in Contour Mode Resonators

Luis Guillermo Villanueva Torrijo, Andrea Lozzi

We here present a study on the influence of metal electrodes on the anchor losses in Contour Mode Resonators (CMRs). Our Finite Element Modelling (FEM) simulation results show that electrode material is key to determine the acoustic losses, and therefore t ...

Robotic training for hand movements during manual welding with real-time alarm feedback

Aude Billard, Mustafa Suphi Erden

Purpose - The purpose of this study is to develop a robotic training system for the hand movements during manual welding. The system provides real-time notice-feedback with sound or light alarms, whenever the welding hand vibrates beyond the nominal level ...
