Control of intermetallics in the interface in directed energy deposition of titanium on stainless steel 316L
Application of a single metal or alloy is often restricted by its properties from optimal combination of performance and cost. Therefore, there is a vast need of joining dissimilar metals for various applications in biomedical, aerospace, automobile and ma ...
EPFL2023Experimental Investigation of Instability-Free Welded Moment Connections With Simplified Weld Details
Dimitrios Lignos, Andronikos Skiadopoulos
In capacity designed steel moment resisting frames, inelastic deformations are mostly concentrated in the steel beams and the column fixed ends of the first story. This design concept limits the participation of the column web’s panel zone in the energy di ...
2023Experimental investigation of the cyclic properties of welds in mild structural steels
Structural steels have long been used in construction applications. Their mechanical properties and behavior under seismic loading or under fatigue design are of considerable interest for researchers and engineers. Although extensive studies have been cond ...
2021Reliability analysis of welded stud shear connectors on simply-supported bridge girders
Scott Walbridge, Matthew James Sjaarda
This paper examines the reliability of welded stud shear connectors for steel-concrete composite bridge girders. A finite element model of a simply-supported bridge was created featuring link connector elements representing the shear studs between beam and ...
CANADIAN SCIENCE PUBLISHING2021Performance of Embedded Bolt Shear Connectors
Scott Walbridge, Matthew James Sjaarda
A laboratory research program carried out at the University of Waterloo featured the testing of three large-scale steel-concrete composite beam specimens with embedded bolt shear connectors. A detailed assessment of the connector performance was made, faci ...
TAYLOR & FRANCIS LTD2020Robotic 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 ...
Institute of Electrical and Electronics Engineers2016Calibration of partial safety factors for fatigue design of steel bridges
Alain Nussbaumer, Luca D'Angelo
The aim of this paper is to propose a new framework for assessment of fatigue partial safety factors with focus on steel bridges welded joints. Fatigue resistance S-N curves for constant amplitude (CA) and variable amplitude (VA) loadings are defined using ...
2015Robotic 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 ...
