The role of microstructure in the thermal fatigue of solder joints
J. W. Xian, Y. L. Xu, S. Stoyanov +3
Thermal fatigue is a common failure mode in electronic solder joints, yet the role of microstructure is incompletely understood. Here, we quantify the evolution of microstructure a…
Slip intermittency and dwell fatigue in titanium alloys: a discrete dislocation plasticity analysis
Yilun Xu, Felicity Worsnop, David Dye +1
Slip intermittency and stress oscillations in titanium alloy Ti-7Al-O that were observed using in-situ far-field high energy X-ray diffraction microscopy (ff-HEDM) are investigated…
An FFT-based crystal plasticity phase-field model for micromechanical fatigue cracking based on the stored energy density
Sergio Lucarini, Fionn P. E. Dunne, Emilio Martínez-Pañeda
A novel FFT-based phase-field fracture framework for modelling fatigue crack initiation and propagation at the microscale is presented. A damage driving force is defined based on t…
Multi-scale plasticity homogenization of Sn-3Ag-0.5Cu: from β-Sn micropillars to polycrystals with intermetallics
Yilun Xu, Tianhong Gu, Jingwei Xian +4
The mechanical properties of -Sn single crystals have been systematically investigated using a combined methodology of micropillar tests and rate-dependent crystal plasticity mo…
A multi-scale approach to microstructure-sensitive thermal fatigue in solder joints
Yilun Xu, Jingwei Xian, Stoyan Stoyanov +4
This paper presents a multi-scale modelling approach to investigate the underpinning mechanisms of microstructure-sensitive damage of single crystal Sn-3Ag-0.5Cu (wt%, SAC305) sold…
Characterisation of microstructural creep, strain rate and temperature sensitivity and computational crystal plasticity in Zircaloy-4
Yang Liu, Weifeng Wan, Said El Chamaa +3
Crystal-level strain rate sensitivity and temperature sensitivity are investigated in Zircaloy-4 using combined of bending creep test, digital image correlation, electron backscatt…
Slip band interactions and GND latent hardening in a galling resistant stainless steel
Benjamin Poole, Fionn P. E. Dunne
Slip activation, slip band interactions, and GND densities in iron-base, galling resistant alloy Nitronic 60 have been characterised at the grain length scale using small-scale mec…
The roles of adhesion, internal heat generation and elevated temperatures in normally loaded, sliding rough surfaces
Benjamin Poole, Bartosz Barzdajn, Daniele Dini +2
The thermal effects of plastic and frictional heat generation and elevated temperature were examined along with the role of adhesion in the context of galling wear, using a represe…
Crystal plasticity analysis of deformation anisotropy of lamellar TiAl alloy: 3D microstructure-based modelling and in-situ micro-compression
Liu Chen, Thomas Edward James Edwards, Fabio Di Gioacchino +3
Detailed microstructure characterisation and in-situ micropillar compression were coupled with crystal plasticity-based finite element modelling (CP-FEM) to study the micro-mechani…
