In hot forming process, the workpiece undergoes plastic deformation at high temperature and the microstructure of the workpiece changes according to the plastic deformation. These changes affect the mechanical properties of workpiece. In order to optimize this process, both the plastic deformation of workpiece and its microstructural changes should be taken into consideration. Since material be...

This work studies the dynamic strain localization and constitutive relationship of a Ti3Al2.5V alloy in jet engine containment system transparent polycarbonate conceived for aircraft canopy application by Digital Image Correlation (DIC) technique from quasi-static condition to high rates at different temperatures. The responses two materials show significant rate temperature sensitivities. Obse...

Amorphous lithium metal alloys (LixM, with M=Si, Ge, Sn, …) are attractive anode materials for lithium-ion batteries owing to their high energy-storage capacity and safety characteristics. However, repeated insertion of often leads chemo-mechanical degradation the alloy, which can severely reduce battery cycle life. Better understanding response is needed guide design damage-resistant microstru...

Many problems in engineering and geophysics feature the free surface flow of a viscoplastic fluid. Although negligible at large scales (e.g. lava flows landslides), capillary forces may become significant small coating polymeric materials 3D printing). The effect yield stress on spreading droplets is considered. Experiments, asymptotic solutions, numerical simulations are used to explain drople...

Abstract. Different polymeric fibrous materials, such as polyester, nylon, aramid and rayon, can be employed reinforcement in tyres or other rubber composites. The present contribution focuses on the experimental characterization of rayon yarns cords makes some steps towards developing a constitutive model for cords, to later integrated into finite element procedure analysis fibre-reinforced Un...
