We use a dynamic finite-difference model to simulate martian landslides in the Valles Marineris canyon system and Olympus Mons aureole using three different modal rheologies: frictional, Bingham, and power law. The frictional and Bingham modes are applied individually. Fluidized rheology is treated as a combination of frictional and power-law modes; general fluidization can include pore pressur...

Computer hardware, and thus computer software, is becoming increasingly complex as facilitated by Moore’s Law. With this swelling of complexity comes an increase in the number and subtlety of design bugs. Traditional simulation-based testing can only increase confidence in design correctness by catching bugs, and can hence allow the subtler bugs to persist into fabricated silicon (for hardware)...

Artificial neural networks (ANN) was used to predict the rheological properties of high temperature pressure gas well cement slurries. Seven different materials were as additives which includes: Fresh water, dyckerhoff, silica flour, antifoam, extender, fluid loss, dispersant, retarder, anti-settling agent, control dry viscosifier, potassium chloride and accelerator. Four recipes prepared using...

A planar two-dimensional computational analysis is presented to qualify traditional and fractal vane-in-cup geometries for accurate rheometry of simple viscoplastic fluids with without slip. Numerical simulations based on an adaptive augmented Lagrangian scheme are used study the flow field yield-stress within around vane tools N=3 24 arms a wide range Bingham numbers, B (i.e. ratio yield stres...

The modeling of fresh concrete flow is still very challenging. Nevertheless, it highest relevance to simulate these industrially important materials with sufficient accuracy. Often, assumed show a Bingham-behavior. In numerical simulations, regularization must be used prevent singularities. Two different models, namely the 1) Bi-viscous, and 2) Bingham-Papanastasiou are investigated. Those mode...

In this paper, a general elastoplastic-damage constitutive model considering the effect of strain rate has been developed. The derivation of this model has been cast into the irreversible thermodynamics with internal variables within the fundamentals of Continuum Damage Mechanics (CDM). The rate effect has been involved as an additional term into the plastic yield surface (dynamic plastic yield...

With the development of plastic surgery techniques, computer aided approach has become a significant method in medical plastic surgery. In order to solve effects on surgical results made by the surface of a wound in craniofacial cosmetic surgery, accurate preoperative preparation is usually required for the surgery. This paper summarizes the application of computer aided technology in craniofac...
