Roundness Evaluation of a Deformed Hole

During manufacturing processes, or during use, the geometrical shape of structural parts can deviate from what was intended. For instance, a hole can deviate from an ideal circle, and it can be important to measure and control this deviation. The process of obtaining this information is often called roundness (or circularity) error evaluation.

This model showcases different methods to estimate the radius and the center of circles that approximate a deformed hole.

Buckling Analysis of a Corrugated Conical Shell

This example illustrates a linear buckling analysis conducted for a corrugated conical shell, utilizing a single sector of the geometry along with cyclic symmetry periodicity edge conditions. The results are compared to those using the full shell geometry.

Nonlinear Ferromagnetic Diaphragm

A magnetic diaphragm is a flexible, thin structure that interacts with magnetic fields to perform mechanical or sensing functions. When subjected to an external magnetic field, the diaphragm deforms due to magnetomechanical interactions, converting magnetic energy into mechanical displacement or, conversely, mechanical deformation into changes in the magnetic field distribution. In this model, the magnetomechanics of a magnetic diaphragm is studied using the Magnetomechanics, Shell multiphysics interface.

Bracket, Explicit Dynamics

This is a tutorial example showing how to perform a drop test using explicit dynamic analysis.

Seismic Event: Scattering off a Small Mountain

The propagation of elastic waves in the ground after a seismic event is simulated using a 2D model. The effect of the ground surface topology on the wave propagation is illustrated when an ideal half-space is modified with the presence of a small mountain. The model is a variation of Lamb's problem. The propagation of the elastic waves is modeled using the Solid Mechanics, Explicit Dynamics interface.

Objects Falling in a Box

This example demonstrates how to set up a dynamic simulation that includes several contact interactions, including friction, using a single general contact pair. The dynamics is solved using explicit time stepping.
