This example involves a static 2D axisymmetric analysis of a piezoelectric actuator using the Piezoelectric Devices physics interface. It models a radially polarized piezoelectric tube, as described by S. Peelamedu and co-authors. An application area where radially polarized tubes are ... Mehr lesen
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 ... Mehr lesen
This example benchmarks a NAFEMS validation model of a friction contact problem with an elastoplastic material model. A thin metal sheet is forced into a die by a punch. Both the compressing displacement and the release of the punch are modeled in order to compute the forming angle (at ... Mehr lesen
A common verification problem for geotechnical problems is a shallow stratum layer of clay. In this example a vertical load is applied on the clay strata and the static response and the collapse load are studied. The clay is modeled as an elastic-perfectly plastic material and the ... Mehr lesen
A hinge between two mechanical components is modeled by coupling two rigid connectors. This method can be used for simulating many types of mechanisms. In mechanical assemblies, parts are sometimes connected so that they are free to move relative to each other in one or more degrees of ... Mehr lesen
In massive forming processes like rolling or extrusion, metal alloys are deformed in a hot solid state with material flowing under ideally plastic conditions. Such processes can be simulated effectively using computational fluid dynamics, where the material is considered as a fluid with ... Mehr lesen
This is a benchmark model involving stick-slip friction of a ring rolling inside another ring. The displacement of the inner ring is computed and compared to the analytical result. This model also shows how to tackle friction dominated contact problem. Mehr lesen
This model illustrates how to implement a multiphysics contact. It models the thermal and electrical behavior of two contacting parts of a switch. The electrical current and the heat flow from one part to the other only through the contact surface. The contact switch device has a ... Mehr lesen
A load carrying component of a structure is subjected to multi-axial cyclic loading during which localized yielding of the material occurs. In this model you perform a low cycle fatigue analysis of the part based on the Smith-Watson-Topper (SWT) model. Due to localized yielding, you ... 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
