High-temperature copolyamides obtained by the efficient transamidation of crystalline-crystalline polyamide blends

Véronique Michaud, John Christopher Plummer, Holger Frauenrath, Sylvain Cyril Claude Galland

High-performance thermoplastic composites based on semiaromatic polyamides are prime candidates for metal replacement in lightweight structural applications. However, the low ductility and toughness of semiaromatic polyamides remain major obstacles to thei ...

Effect of charging/discharging on plasticity and fracture in Si anodes for batteries

Seyed Mostafa Khosrownejad

Lithium-ion batteries provide the power for portable electronics and found many other interesting applications. It is desirable to design batteries with high energy density and long cycle life. Silicon is among the highest Li-storing anode materials in bat ...

Influence of Lap Splices on the Deformation Capacity of RC Walls. II: Shell Element Simulation and Equivalent Uniaxial Model

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Danilo Tarquini

Spliced longitudinal reinforcement may result in a reduction of both strength and displacement capacity of reinforced concrete (RC) members. This applies in particular when lap splices are located in regions where inelastic deformations concentrate, such a ...

Model for charge/discharge-rate-dependent plastic flow in amorphous battery materials

William Curtin, Seyed Mostafa Khosrownejad

Plastic flow is an important mechanism for relaxing stresses that develop due to swelling/shrinkage during charging/discharging of battery materials. Amorphous high-storage capacity Li-Si has lower flow stresses than crystalline materials but there is evid ...

Mean-Field Description of Plastic Flow in Amorphous Solids

Matthieu Wyart, Jie Lin

Failure and flow of amorphous materials are central to various phenomena including earthquakes and landslides. There is accumulating evidence that the yielding transition between a flowing and an arrested phase is a critical phenomenon, but the associated ...

Effect of surface films on tribologically induced metallurgical transformations of steel in oil lubricated contacts

Stefano Mischler, Marco Cantoni, Shoufan Cao

This study was initiated with the aim to assess the influence of boundary films on the tribologically induced metallurgical transformations and deformations of metals in lubricated contacts and their effect on wear. For this, the tribological behavior of a ...

Energetics of dislocation transformations in hcp metals

William Curtin, Binglun Yin, Zhaoxuan Wu

Dislocation core structures of hcp metals are highly complex and differ significantly among the hcp family. Some dislocations undergo unconventional transformations that have significant effects on the material plastic flow. Here, the energetics of disloca ...
