A lot of contact results can be accessed using the Contact Tool, but to obtain contact forces we use Probes. This case corresponds to an infinite friction coefficient between the contacting bodies. These names might be called with different names according to softwares. ANSYS Mechanical, Contact, Contact Forces, Post processing, Probes Recently we have had a few questions on obtaining contact results in ANSYS Mechanical. By default, no automatic closing of gaps is performed. It only applies to regions of faces (for 3D solids) or edges (for 2D plates). Similar to the frictionless setting, these setting models perfectly rough frictional contact where there is no sliding. The coefficient of friction can be any nonnegative value.
Once the shear stress is exceeded, the two geometries will slide relative to each other. This state is known as “sticking.” The model defines an equivalent shear stress at which sliding on the geometry begins as a fraction of the contact pressure. In this setting, the two contacting geometries can carry shear stresses up to a certain magnitude across their interface before they start sliding relative to each other. Weak springs are added to the assembly to help stabilize the model in order to achieve a reasonable solution. The model should be well constrained when using this contact setting.
A zero coefficient of friction is assumed, thus allowing free sliding.
This solution is nonlinear because the area of contact may change as the load is applied. Thus gaps can form in the model between bodies depending on the loading. This setting models standard unilateral contact that is, normal pressure equals zero if separation occurs. Slide is possible, but the nodes in contact are bonded to the target surface in normal direction. No separation contact: Once the contact is detected, then the target and contact surface are tied up for the rest of the analysis. If contact is determined on the mathematical model, any gaps will be closed and any initial penetration will be ignored. In this course, we will use the ideas of engineering simulation to. Due to its nonlinear nature, contact mechanics is still one of toughest problems in solid mechanics. This type of contact allows for a linear solution since the contact length/area will not change during the application of the load. An accurate understanding of stress and deformation arising from contact is critical for the design of reliable, efficient and safe products such as disc brakes, gears and tires. is strictly prohibited and may be subject to penalties under the Uniform Trade Secrets Act and other laws.

If contact regions are bonded, then no sliding or separation between faces or edges is allowed. Siebel eCustomer Portal Innovation Pack 2013. That should follow the results of the light gap.This is the default configuration and applies to all contact regions (surfaces, solids, lines, faces, edges). I definitely need contact pressure and that can't be zero. How can I run the simulation so that the ring at the end presses the cylinder wall? That means the ring is only on the surface, although I did not use "Adjust to touch". but in the contact tool the pressure is zero everywhere. Where the light gap is zero, there must be pressure (from the spring force of the ring). But in the contact tool I get strange results. Now I have to evaluate the contact pressure and the light gap. Everything had worked great as you can see on the third picture. I used a frictionless contact and applied a load moment to the transverse surfaces of the ring.
Hello Ansys Community!!! A month ago I got help on how to print a ring in a cylinder without a force in the last step.
