Strain engineering and strain measurement by spring tethers on suspended epitaxial GaN-on-Si photonic crystal devices
Suspended epitaxial gallium nitride (GaN) on silicon (Si) photonic crystal devices suffer from large residual tensile strain, especially for long waveguides, because fine structures tend to crack due to large stress. By introducing spring-like tethers, des ...
Bristol2024Experimental and ab initio derivation of interface stress in nanomultilayered coatings: Application to immiscible Cu/W system with variable in-plane stress
Pandula Manura Liyanage, Claudia Cancellieri, Giacomo Lorenzin
Interface stress is a fundamental descriptor for interphase boundaries and is defined in strict relation to the interface energy. In nanomultilayers with their intrinsically high interface density, the functional properties are dictated by the interface st ...
Elsevier2024Strain-based analysis on the influence of local undercut geometry on fatigue crack initiation life
Alain Nussbaumer, Heikki Tapani Remes, Abinab Niraula
The local undercut defects at the weld toe provide a potential initiation site for fatigue cracks and significantly impact the structure's fatigue strength. The influence of continuous undercut depth on fatigue performance is widely studied, but the resear ...
2024A pre-fatigue training strategy to stabilize LiCoO2 at high voltage
Lei Zhang, Kangning Zhao, Rui Xia
Layered cathodes are among the most promising cathodes for high-energy-density Li-ion batteries, yet hindered by the structural degradation from both bulk strain and surface oxygen loss at high voltage (above 4.5 V). Herein, we report a pre-fatigue trainin ...
Cambridge2024Extension of the OFFBEAT fuel performance code to finite strains and validation against LOCA experiments
Andreas Pautz, Carlo Fiorina, Alessandro Scolaro, Edoardo Luciano Brunetto
The mechanical analysis of nuclear fuel behavior under base-irradiation conditions has traditionally been performed adopting the small-strain approximation. However, many cases of interest for fuel behavior involve the occurrence of large rod deformations ...
ELSEVIER SCIENCE SA2023On the slip burst amplitude cutoff in dislocation-rich microcrystals
Andreas Mortensen, Luciano Borasi
The plastic deformation of small-scale face-centered cubic metals exhibits intermittent slip burst events that appear on stress-strain curves as sudden strain jumps and/or load drops. These events are generally attributed to the avalanche-like cooperative ...
