In this example, the Extended Barcelona Basic Model (BBMx) is used to model oedometer, uniaxial swelling, triaxial, and constrained swelling tests on bentonite clays in order to recover the hydromechanical characteristics of the soil samples. There is a good qualitative agreement ... Mehr lesen
Lamb-wave resonators are useful components for many radio-frequency applications. This example shows how you model an aluminum nitride Lamb wave resonator and perform eigenfrequency and frequency-response analyses to characterize the device. The tutorial uses the Electric Currents in ... Mehr lesen
A Fresnel lens can be constructed from a plano-convex lens as a way to reduce the thickness. This model models the collimation property of a Fresnel lens and demonstrates the geometry operation of making a Fresnel lens from a plano-convex lens. Mehr lesen
A thin-walled metal frame with a central cutout, modeled using the Shell interface, is subjected to twisting and bending. Around the cutout the stresses are higher than the yield stress, thus the material undergoes plastic deformation over the loading history. Mehr lesen
The purpose of this application is to generate response spectra from a time history which can consist of either measured data on a file, or an analytical function. Primarily, the target is to provide input to a response spectrum analysis. The graphs can, however, also be used to ... Mehr lesen
In this example, triaxial and oedometer tests are simulated using the Modified Cam-Clay material model. A nonlinear stress-strain relation is recovered with the constant Poisson's ratio formulation. The hardening and softening behavior is recovered for normally consolidated and highly ... Mehr lesen
In this example, a settlement and heave analysis of a shallow foundation resting on an unsaturated soil stratum is conducted with the Modified Cam-Clay and Extended Barcelona Basic soil models. The effect of pore suction due to movements in the phreatic line and the resulting settlement ... Mehr lesen
This model presents a solution to the Transient Electromagnetic Analysis Methods (TEAM) workshop problem 28, “An Electrodynamic Levitation Device”- a benchmark problem involving the dynamic coupling of electromagnetics and rigid body dynamics. An electrodynamic levitation force is ... Mehr lesen
Steel pipelines are often subjected to complex stress/strain conditions in the oil and gas industry. Additionally, pipes are subjected to significant longitudinal strain due to soil movement. For the elastoplastic stress simulation, the Solid Mechanics interface is used with the small ... Mehr lesen
This models pressure-dependent heating of 4 inch wafer on unipolar electrostatic chuck. Wafer sits on top of ring with electrostatic force holdong down wafer to counter upward pressure from gas flowing in gap between wafer and chuck surface. It is a problem involving 4 coupled physics ... Mehr lesen
