In this tutorial model, it is demonstrated how to incorporate a localized nonlinearity in a submodel. In this case, an initial elastic analysis reveals that a small region of a structure has stresses above the yield limit. To improve the results, an elastoplastic material model is added ...

This is a benchmark model for flexible multibody dynamics. This model simulates the dynamic behavior of a planar four-bar mechanism when one of the joints has a defect. The out-of-plane motion in the mechanism, caused by the defect in the joint, is compared with the results from the ... Mehr lesen
This example shows how to compute the critical buckling load in the presence of dead loads. A truss tower is supported by pretensioned guys. The pretension load and gravity on the truss are considered as dead loads, while the vertical load applied at the top of the tower is considered ... Mehr lesen
In this tutorial model, a step thrust bearing is shape optimized to maximize the bearing capacity. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to be ... Mehr lesen
In this example, a spring-loaded valve-opening mechanism consisting of a rocker arm and a radial cam is studied. All of the system components are modeled as rigid and are connected through prismatic, hinge, and slot joints. The cam-follower connection as well as other joint connections ... Mehr lesen
A thin-walled container made of rolled steel is subjected to an internal overpressure. As an effect of the manufacturing method, one of the three material principal directions—the out-of- plane direction— has a higher yield stress than the other two. Hill’s orthotropic plasticity is used ... Mehr lesen
This model sets up a linear array of nine tonpilz piezoelectric transducers in a 3x3 grid. A voltage is applied that includes a phase change across the three rows. The transducers are located in a box below the sea surface. The exterior acoustics are modeled using the Pressure ... Mehr lesen
This example presents a homogenized model of a corrugated sheet based on a unit cell approach. The numerically obtained equivalent stiffness matrices are compared with various analytical models. Two corrugation profiles, trapezoidal and round, are considered in this example. Mehr lesen
The problem of a plane wave scattering off a cylinder-shaped object suggests the use of the 2D axisymmetric formulation. This can save computation time and reduce the memory usage compared to the model in 3D space. This example demonstrates the use of the built-in plane wave expansion ... Mehr lesen
This is a small 2D demonstration model that couples the Linearized Navier-Stokes, Frequency Domain, Solid Mechanics, and Turbulent Flow (k-epsilon) physics interfaces to model the vibrations of a plate located in a 2D viscous parallel plate flow. This type of model is used to model fluid ... Mehr lesen
