Time-dependent behavior of Fe-based Shape Memory Alloys: A Comprehensive Analysis of Creep, Stress Relaxation, and Corrosion Behavior for Concrete Reinforcement Applications

Meet Jaydeepkumar Oza

Shape memory alloys (SMAs) exhibit unique characteristics, enabling them to recover their original shape either upon unloading (pseudoelasticity) or through heating (shape memory effect, SME). Due to their exceptional mechanical properties, the SME, and th ...

Adhesive wear mechanisms in the presence of weak interfaces: Insights from an amorphous model system

Jean-François Molinari, Tobias Brink

Engineering wear models are generally empirical and lack connections to the physical processes of debris generation at the nanoscale to microscale. Here, we thus analyze wear particle formation for sliding interfaces in dry contact with full and reduced ad ...
