Adaptive Health Monitoring Concepts for Spot-welded and Weld-bonded Structural Joints
The health monitoring of structural joints is a major concern of the engineering community and needs to be addressed with the proper consideration. Among joining techniques, the spot welding and weld-bonding (spot weld + adhesive bonding) methods are of great interest in a number of industries. Spot welding is the traditional assembly method for steel-based automotive structures, while weld-bon...
متن کاملE/m Impedance Health Monitoring of Spot-welded Structural Joints
1 TRACT erimental results obtained during fatigue testing of a lded lap-shear structural-joint specimen are d. In these experiments, the electro-mechanical mpedance technique was used for structural health ing, damage detection, and NDE. The test ns were instrumented with piezo-electric wafer ers, and the base E/M impedance signature was over the relevant frequency range. Fatigue testing lied t...
متن کاملEffect of Weld Metal Microstructure on the Fatigue and Corrosion-Fatigue Properties of GTA-Welded 304 Stainless Steel
In this research, two different filler metals, ERNiCrMo-3 and ER309L, were used for developing different microstructure, austenite (γ) and austenite and ferrite (γ+δ) in the weld metal and fatigue properties of welded samples were evaluated in the air and sea water environments. Microstructural studies indicated a good agreement between predicted microstructures via schiffler diagram and metall...

متن کاملFatigue Life Assessment of Welded Joints Considering Crack Propagation Based on Hot Spot Stress
In this study, fatigue test and crack propagation analysis of welded joints in ships and offshore structures were performed. The test models have two types of welded joints, T-joint and double plate. Test data is presented in S-N curves obtained by the Hot Spot Stress (HSS) approach. The S-N data for each length of crack were appraised to define the fatigue life of crack initiation and propagat...
