Scordelis-Lo Roof Shell Benchmark

In this example a thin curved membrane is built and solved using the Shell interface. This model is a widely used benchmark model denoted the Scordelis-Lo roof. The computed maximum z-deformation is compared with the value given in Proposed Standard Set of Problems to Test Finite Element Accuracy, Finite Elements in Analysis and Design, 1985.

Stress Analysis of an Elliptic Membrane

This is a benchmark model for a plane stress problem. The accuracy of the computed stress concentration is evaluated, and a mesh convergence study is performed for different element types.

Vibration Analysis of a Thick Beam

This model studies free and forced vibrations of a deep beam. The solution for eigenfrequency, frequency response and transient analysis are computed using a Timoshenko beam and compared with analytical results.

Connecting Shells and Solids

This tutorial model shows how to model a structure using both shells and solids, and how to create the transition between the two modeling domains. Results are compared between the shell solution and the full 3D solution, and the effects of the transition are highlighted.

Piezoelectric Tonpilz Transducer with a Prestressed Bolt

A tonpilz transducer is used for relatively low frequency, high power sound emission. It is one of the popular transducer configurations for SONAR applications. The transducer consists of piezoceramic rings stacked between a head mass and a tail mass which are connected by a central bolt. This example shows how to incorporate the effect of a pre-tension in the bolt. The bolt geometry is imported ...

In-Plane Framework with Discrete Mass and Mass Moment of Inertia

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 model. The two first eigenfrequencies are compared with the values given by an analytical expression.

In-Plane and Space Truss

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 truss model using the 2D Truss interface. Later on, you analyze a 3D variant of the same problem using the 3D Truss interface. This model calculates the deformation ...

Thermally Loaded Beam

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 well as the left and right surfaces of the beam. The calculated solution is compared to the analytical solution.

Pinched Hemispherical Shell

This example studies the deformation of a hemispherical shell, where the loads cause significant geometric nonlinearity. The maximum deflections are more than two magnitudes larger than the thickness of the shell. The problem is a standard benchmark, used for testing shell formulations in a case which contains membrane and bending action, as well as large rigid body rotation.

MEMS Pressure Sensor Drift due to Hygroscopic Swelling

Modern integrated circuits are available as plastic encapsulated microcircuits (PEM). These devices are molded out of polymeric materials and epoxy resins in order to protect the internal semiconductors. Unfortunately, polymeric mold compounds absorb moisture when exposed to a humid environment, thus swelling and causing undesired strains, which can be as high as thermal strain. This model ...
