Usually, in integrated circuits, the chip is brazed on leadframe and then, a polymer resin is molded around to create the packaging. On the first hand, the molding process at high temperatures will induce thermomechanical stress on the chip. As the leadframe, the chip and the braze have ... Mehr lesen
The Spark Plasma Sintering is a breakthrough way of elaboration of more or less complex shape materials from powder. This process allows the sintering of materials in few minutes compare to hours by conventional sintering. One of the main goals of the SPS modeling is to be able to ... Mehr lesen
Manual wheelchair users suffer shoulder pain and injury in the long term because of unconscious overuse. The ‘SENSEWHEEL’, which interposes three identical load cells between pushrim and rear wheel, measures the three components of pushing force Fx, Fy and Fz, and axial torque Tx ... Mehr lesen
Puffing of biomaterials involves mass, momentum and energy transport along with large volumetric expansion of the material. Development of physics-based models that can describe heat and moisture transport, rapid evaporation and large deformations can help understand the puffing process. ... Mehr lesen
A research team at FSU CAPS is developing a novel fast disconnect switch based on a piezoelectric actuator for use in next-gen electric power distribution systems. COMSOL Multiphysics® software was used to optimize geometry and material selection of the disconnect switch. Current ... Mehr lesen
The ubiquitous commercial use of Lithium-Ion batteries (LIBs) has increased interest in their implementation into efficient energy storage systems for clean and renewable power sources and the electrical transportation industry. Unfortunately, LIBs are not yet technological mature to ... Mehr lesen
Turgor pressure loss and pectin degradation result in texture loss during cooking of plant based materials. To simulate texture loss, a simultaneous heat and moisture transfer, pectin degradation in the cell wall material and solid mechanical model was developed at the microscale using ... Mehr lesen
