Tailored Mechanical Response of 3D Microgranular Crystals with Hierarchical Architecture
… simulations uncover a structurally engineered Poisson effect, enabling nonlocal contact mechanisms that enhance load-bearing capacity across different packing structures. Future custom direct impact experiments demonstrate a potential route the effectiveness of our multi-scale design in …

Design of width-extensional, piezoelectric RF MEMS resonators and filters
… or filter array can be fabricated. However, the effect of disorder in a group of resonators can be reduced with mechanical coupling. Therefore, we present a novel approach that is disorder tolerant, allowing for the fabrication of higher frequency, lower impedance LBAR-based resonators and …

Modeling, simulation, and control of a polypyrrole-based conducting polymer actuator
… loads result in a negligible electrical back effect. This is surprising, suggesting that there are huge entropic losses when applying mechanical loads. After examining the mechanics of the system it was theorized that the apparent lack of coupling is actually the result of the Poisson Effect, …

Numerical investigation of the edge profile in hot-rolling
… is not constrained laterally; and due to the Poisson effect, the material spreads outward near the surfaces, and moves inward at the centre. The effect of certain variables on the edge profile were investigated with the modelling. The friction between the work-rolls and the ingot was found to …

Material Related Effects on the Structural Thermal Optical Performance of a Thermally Tunable Narrowband Interferometric Spectral Filter
High Spectral Resolution Lidar (HSRL) is a backscatter lidar technique that employs an optical/spectral filter to distinguish between particulate (Mie) and molecular (Rayleigh) backscattered light. By separating the two types of returns, higher accuracy measurements are possible that will enable …
