Parameterized Concrete Beam
Reinforced concrete beams are commonly used in modern construction due to their strength and durability. By simulating such beams, engineers can ensure that the resulting structures both perform well and are safe. With simulation apps, engineers of all levels of expertise can analyze and test different designs with ease. The Parameterized Concrete Beam demo app focuses on the structural ...
Accelerated Life Testing
Fatigue testing of nonlinear materials with creep mechanism is a time consuming process. In accelerated life testing the experiment time is greatly reduced by subjecting the material to testing conditions in excess of the operating one. In the model an aggressive thermal load cycle is simulated and its effect on the fatigue life of a solder joint is examined. This example demonstrates how to ...
Motion of Trapped Protons in Earth's Magnetic Field
This model demonstrates the path of non-relativistic protons within Earth's magnetic field. Due to the dipole nature of Earth's magnetic field, charged particles, such as electrons and protons, can get trapped in stable configurations within it for long periods of time. These configurations involve the particles rapidly bouncing from magnetic pole to magnetic pole, and drifting around the ...
Caughey-Thomas Mobility
With an increase in the parallel component of the applied field, carriers can gain energies above the ambient thermal energy and be able to transfer energy gained by the field to the lattice by optical phonon emission. The latter effect leads to a saturation of the carriers mobility. The Caughey Thomas mobility model adds high field velocity scattering to an existing mobility model (or to a ...
Kirsch Infinite Plate Problem
This model describes a static stress analysis to obtain the stress distribution in the vicinity of a small hole in an infinite plate. The model is a classic benchmark and is described in Mechanics of Material, by D. Roylance. The stress level is then compared with the theoretical values.
Electrocoating of a Car Door
This example models electrocoating of paint onto a car door in a time-dependent simulation. The deposited paint is highly resistive which results in lowered local deposition rates for coated areas. A primary current distribution in combination with a film resistance model is used to describe the charge transport in the electrolyte. The model is in 3D and uses an imported CAD geometry.
Geometric Parameter Optimization of a Tuning Fork
This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from SolidWorks via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz.
Programming of a Floating Gate EEPROM Device
This model calculates the current and charge characteristics of a floating gate Electrically Erasable Programmable Read-Only Memory (EEPROM) device. A stationary study demonstrates the effects of varying the charge stored on the floating gate by computing Current-Voltage curves as a function of the control gate voltage for two different amounts of stored charge. Time dependent studies are then ...
Centrifugal Governor Simulator
Centrifugal governors, a specific type of governor, control the speed of an engine by regulating the amount of admitted fuel. In order to maintain a near-constant speed, regardless of the load or fuel supply conditions, centrifugal governors use the principle of proportional control. While the governor is in operation, it is critical that it quickly reaches a new steady-state configuration. ...
Characteristic Parameters of a Coaxial Cable
Electrical cables, also called transmission lines, are used everywhere in the modern world to transmit both power and data. These cables carry electromagnetic energy, but instead of dealing with the full complexity of the electromagnetic fields, they are more commonly classified according to parameters such as capacitance, inductance, and impedance. In this model of a coaxial cable, we ...
