This model describes a static stress analysis to obtain the stress distribution in the vicinity of a small hole in an infinite plate. The model is a classic benchmark and is described in Mechanics of Material, by D. Roylance. The stress...
In many structural dynamics applications, some components are stiff compared to the supporting structure. Such a stiff part will only contribute to the dynamic properties of the structure through its mass and moment of inertia. It is then...
This example shows how to parameterize a CAD model by deforming the corresponding finite element mesh. The method enables geometry parameterization of non-parameterized CAD models such as: - models created by the built-in COMSOL...
A frame with a central cutout is subjected to a random load consisting of 1000 load events. The external load, recorded using three strain gauges, is simulated using superposition of three unit loads. The stress state around the cutout is...
One way to fasten a gear to a shaft is by thermal interference. In preparation of the assembly, the shaft diameter is oversized and the gear thermally expanded in a heat-treating oven. At an appropriate expansion state, the gear is...
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.
The most common reason that people have hip-replacement surgery is due to the wearing down of the hip joint that results from osteoarthritis. Other conditions, such as rheumatoid arthritis (a chronic inflammatory disease that causes joint...
A thick wall cylinder is exposed to both internal and external pressure and thermal load. The model is both plane and axisymmetric. The results are compared to the analytic solution.
