ANSYS software, Mechanics of machine, XXIII, book 5, pp. When the coordinate system is chosen to coincide with theeigenvectors of the stress tensor, the stress tensor is represented bya diagonal matrix Explicit dynamics analysis follows next major steps, described below and shown graphically on. Independent of the coordinate system used The stress tensor itself is a physical quantity

Volumetric Response - changes in volume (pressure)Īlso, it is often necessary to specify a Failure model as materialscan only sustain limited amount of stress / deformation before theybreak / crack / cavitate (fluids).Ī stress state in 3D can be described by a tensor with six stresscomponentsĬomponents depend on the orientation of the coordinate system used.

If you are interested in building and performing similar scenarios, you can download their MECHDAT files to see the necessary settings we used for mesh, loads, time steps etc., together with the 3D models. These asteroids or planetoids are minor planets of the inner Solar System which can be very big and usually travelling with very high speeds.Explicit Dynamics Chapter 9 Material ModelsĢ009 ANSYS, Inc. ANSYS Workbench Explicit Dynamics FEA of a hollow cylinder hitting a fan. Every year we are hearing that a dangerous asteroid is approaching earth. In mechanical science, an impact is a high force or shock applied over a short period when two or more bodies collide.
✍️ How can we simulate an asteroid impact with earth? Ansys explicit dynamics gives us a strong and robust tool to see the real effects of such a phenomenon.
