This work gives an overview of the theoretical and experimental achievements of mechatronics applied to fluid film bearings. Compressible and uncompressible fluids are addressed. Rigid and elastic (deformable) bearing profiles are investigated. Hydraulic, pneumatic, magnetic and piezoelectric actuators are used. The ideas of combining control techniques, informatics with hydrodynamic, thermo-hy...

The dynamics of a flexible filament sedimenting in a viscous fluid are explored analytically and numerically. Compared with the well-studied case of sedimenting rigid rods, the introduction of filament compliance is shown to cause a significant alteration in the long-time sedimentation orientation and filament geometry. A model is developed by balancing viscous, elastic and gravitational forces...

We report a Raman scattering study of nematic degrees freedom in the iron-based superconductor parent compound BaFe$_2$As$_2$ under tunable uniaxial strain. demonstrate that polarization resolved arsenic (As) phonon intensity can be used to monitor order parameter as function both temperature and At low ordered phase we use it track continuous reversible orientation domains variable higher temp...

We present an alternative approach to standard geometric shape editing using physically-based simulation. With our technique, the user can deform complex objects in real-time. The enabling technology of this approach is a fast and accurate finite element implementation of an elasto-plastic material model, specifically designed for interactive shape manipulation. Using quadratic shape functions,...

Cemented backfill is one of geomaterials which is used at a high volume to serve a variety of geo-infrastructure systems, e.g., embankments, retaining walls and approach abutments, and involves the solidification of soil or similar fine aggregate through the addition of a controlled amount of cementitious materials, such as Portland cement, fly ash or lime. A certain volume of expanded polystyr...

We present a numerical algorithm for the simulation of the impact of hyperelastic-viscoplastic materials in two dimensions. There are several distinctive aspects of our approach. The governing equations are based on a fully conservative Eulerian formulation due to Plohr and Sharp and our modiication of the Steinberg-Lund rate dependent plasticity model. An approximate 2D Riemann solver is const...
