Laminated composite shells made from graphite–epoxy fiber-reinforced plies are widely used in many applications due to their high strength-to-weight ratio. Evaluating their structural integrity under applied loads is essential for ensuring reliable designs. This example demonstrates ... En savoir plus
This example shows how to set up a piezoelectric transducer problem following the work of Y. Kagawa and T. Yamabuchi. The composite piezoelectric ultrasonic transducer has a cylindrical geometry that consists of a piezoceramic layer, two aluminum layers, and two adhesive layers. The ... En savoir plus
Chain drives are used for transmitting power from one shaft to another, located at some distance. This example demonstrates how to model a chain sprocket assembly in 3D. The geometry consists of a roller chain wrapped around two sprockets. All components are assumed to be elastic. The ... En savoir plus
This app demonstrates the following: Selecting predefined or user-defined materials User option to switch between laminar flow or turbulent flow Changing boundary conditions using methods Visualizing temperature dependent material properties as graph plots User option to set the solver ...

In small PEM fuel cell systems (in the sub-100 W range) no active devices for cooling or air transport are normally used. This is due to the desire to minimize parasitic power losses from pumps and fans, and to reduce the system complexity, size, and cost. The reactants at the cathode ... En savoir plus
Non-Newtonian fluids have complex flow characteristics that vary with shear rate, making their behavior in porous materials difficult to predict. Pore scale modeling captures these flow patterns at a microscopic level, helping derive properties for macroscale use. This model ... En savoir plus
This model simulates a plasma at medium pressure (2 torr) where the plasma is still not in local thermodynamic equilibrium. At low pressures the two temperatures are decoupled but as the pressure increases the temperatures tend towards the same limit. En savoir plus
This tutorial model demonstrates how to estimate the material parameters of a viscoplastic Bergstrom–Boyce model suitable for nonequilibrium modeling of rubber-like materials. The data used for parameter estimation consists of cyclic uniaxial tension and compression tests at two ... En savoir plus
This example illustrates how to model a barrel hinge connecting two solid objects in an assembly. In this model, the details of the connection are not the focus of the analysis, therefore, the hinge joint is modeled using a Joint feature in the Multibody Dynamics Module. The connected ...

A vessel traveling on the surface or under water gives rise to detectable local disturbances in the Earth’s magnetic field. These disturbances can be used to trigger weapon systems. The magnetic signature of a ship can be reduced by generating a counteracting magnetic field of suitable ... En savoir plus
