Experimental Characterization and Constitutive Modeling of the Effect of Prior Inelastic Strain on the Viscoplastic Behavior of AD730 at 700 °C

Advanced Engineering Materials, EarlyView.
This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Physical models for smart-power devices

Proceedings of the International Conference Mixed Design of Integrated Circuits and System, 2006. MIXDES 2006., 2006
A careful prediction of the carrier mobility and impact-ionization generation is essential for the design of devices working in high-current/voltage conditions, where self-heating is relevant. Recently, some of the authors presented new physically-based models for both mobility and impact ionization, which have been validated up to very high operating ...

On the physical meaning of the power factor in acoustics

The Journal of the Acoustical Society of America, 2012
Following recent advancements in the study of time-averaged properties of energy propagation in linear acoustic fields, the well established concept of power factor known from the electric AC circuits analysis, is here extended to acoustics. This allows our outline of a complete acousto-electro-mechanic analogy, where the fundamental physical concept ...
