We study spontaneous deformations of a ribbon made of nematic polymer networks and activated under the action of a mechanical load. We show that when such ribbons are activated appropriately, the deformations produced can ...

Condensation of water vapor on nonwetting surfaces, termed dropwise condensation, leads to rapid droplet removal and significantly improves heat transfer compared to wetting surfaces. However, the spatial distribution of ...

Orthopedic and dental implants made from Ti6Al4V are widely used due to their excellent mechanical properties and biocompatibility. However, the long-term performance of these implants can be compromised by bacterial ...

A one-dimensional diffusion-based damage-healing (EPDH) model for elasto-plastic self-healing materials, based on Lemaitre’s ductile damage, is developed. The novelty of proposed model is focused on capturing the diffusion-based ...

A wide range of industrial applications rely heavily on heat transfer during vapor condensation from a mixture of water vapor and noncondensable gases (NCG). For a vertically-mounted condenser plate, the vapor-diffusion ...

A one-dimensional constitutive model, based on the principles of continuum damage mechanics, is developed for capturing healing in certain materials during unloading and rest periods. A secondary damage variable is defined ...

The utilisation of flaky aluminium as an additive in the composite matrix has shown the ability to overcome the brittle nature encountered in epoxy resins. The additive increases the overall composite toughness without ...

Strengthening during low-temperature annealing is a common observation in several nanocrystalline and ultrafine-grained materials. The origin of such strengthening is generally attributed to various recovery processes ...
