How do you choose master and slave surface?

Slave and master surfaces

1. the slave surface should be the more finely meshed surface; and.
2. if the mesh densities are similar, the slave surface should be the surface with the softer underlying material.

What is a slave surface?

Thus, the slave surface can be defined as a group of nodes—a node-based surface. Node-to-surface discretization is available even if a node-based surface is not used in a contact pair definition.

How is general contact defined in Abaqus?

In Abaqus/Explicit you can obtain contact data for a specific surface in the general contact domain by using the history output request editor in the Step module. In the Domain section of the editor, select General contact surface and choose the surface from the menu that appears.

What is position tolerance in Abaqus?

By default, ABAQUS uses a position tolerance criterion to determine the constrained nodes based on the distance between the slave nodes and the master surface. Alternatively, you can specify a node set containing the slave nodes to be constrained regardless of their distance to the master surface.

What is the difference between master and slave surface in Abaqus?

Analytical rigid surfaces and rigid-element-based surfaces must always be the master surface. A node-based surface can act only as a slave surface and always uses node-to-surface contact. Slave surfaces must always be attached to deformable bodies or deformable bodies defined as rigid.

What is tie constraint in Abaqus?

A tie constraint ties two separate surfaces together so that there is no relative motion between them. This type of constraint allows you to fuse together two regions even though the meshes created on the surfaces of the regions may be dissimilar.

What are contact pairs in Abaqus?

You can define contact in Abaqus/Standard in terms of two surfaces that may interact with each other as a “contact pair” or in terms of a single surface that may interact with itself in “self-contact.” Abaqus/Standard enforces contact conditions by forming equations involving groups of nearby nodes from the respective …

What is pressure Overclosure in Abaqus?

In Abaqus the following contact pressure-overclosure relationships can be used to define the contact model: a “softened” contact relationship in which the contact pressure is a piecewise linear (tabular) function of the clearance between the surfaces; and.

What is a tie constraint in Abaqus?

What is MPC constraint in Abaqus?

An MPC constraint allows you to constrain the motion of the slave nodes of a region to the motion of a single point. For detailed instructions on creating this type of constraint, see “Defining MPC constraints,” Section 15.15.5. A multi-point constraint between two points is defined using connectors.

What is master slave tracking?

Thermal Master-Slave Tracking System is formed by one fixed bullet camera and one PTZ camera. The PTZ camera smartly tracks multiple moving targets, and the fixed camera offers the panoramic view. When thermal camera detects the Intrusion or Line Crossing, it will trigger the PTZ camera to track.

What is the difference between small sliding and finite sliding in Abaqus?

finite sliding, which is the most general and allows any arbitrary motion of the surfaces; small sliding, which assumes that although two bodies may undergo large motions, there will be relatively little sliding of one surface along the other; or.
