A benchmark model where a thick plate exposed to pressure on the top surface is analyzed. The solution is compared with a NAFEMS benchmark solution.
This model studies the natural frequencies of a pre-tensioned string using the 2D Truss interface. This is an example of “stress stiffening”; in fact the transverse stiffness of truss elements is directly proportional to the tensile...
Viscoelastic materials have a time-dependent response, even if the loading is constant. Many polymers and biological tissues exhibit such a behavior. Linear viscoelasticity is a commonly used approximation, where the stress depends...
This model is compared to a NAFEMS benchmark for composite material modeling, No R0031/2. The geometry is a long, thick, and hollow cylinder consisting of two layers, where an internal pressure is applied. The inner layer is made from an...
In this example you will build and solve a 3D beam model using the 3D Beam interface. This model shows how a thermally induced deformation of a beam is modeled. Temperature differences are applied across the top and bottom surfaces as...
The rotor in an electric motor is analyzed. In the design of a motor it is important that no eigenfrequencies for the rotor lie within the operating interval of the revolution speed (in revolutions / second) for the motor. If the...
A plate modeled using the Plane Stress interface is loaded above the elastic limit. The material is elastoplastic with isotropic hardening. The plot shows the plastic zone.
In this model, a thick square plate is excited by a harmonic uniform pressure. A frequency sweep is performed to find the frequency with maximum displacement. The solution is compared with a NAFEMS benchmark
Trusses are elements which can only sustain axial forces. You can use trusses to model truss works where the edges are straight as well structures like sagging cables. In the following example you first build and solve a simple 2D...
In this model, you build and solve a 2D beam model using the 2D Structural Mechanics Beam interface. This model describes the eigenfrequency analysis of a simple geometry. A point mass and point mass moment of inertia are used in the...
