Now you will define contact between regions of the model.
There are two approaches that can be adopted to define contact
interactions. The first is a manual approach that requires you to identify
which surfaces will form part of the contact interactions and to define the
individual contact pairs. An alternative approach is to let
Abaqus/CAE
automatically identify and define all potential contact pairs. The latter
approach is desirable for complicated models containing many contact
interactions. The automatic contact definition option is available only for
three-dimensional
Abaqus/Standard
models.
In
Defining contact between regions of the model
you will be given the option to define the contact interactions either manually
(where you will use the surfaces defined in the following instructions) or
automatically (in which case the surfaces defined below are not used;
Abaqus/CAE
will choose the surfaces automatically). For instructional purposes, however,
you are encouraged to complete the surface definition instructions that follow
regardless of the approach you choose to define the contact interactions.
When manually defining contact interactions, the first step is to create
the surfaces that you will include later in interactions. It is not always
necessary to create your surfaces in advance; if the model is simple or the
surfaces easy to select, you can indicate the master and slave surfaces
directly in the viewport as you create the interactions. However, in this
tutorial it is easier to define the surfaces separately and then refer to the
names of those surfaces when you create the interactions. You will define the
following surfaces:
A surface named Pin that includes the
outside surface of the pin.
Two surfaces named Flange-h and
Flange-s that include the two flange faces that
contact each other.
Two surfaces named Inside-h and
Inside-s that include the inside surfaces of the
flanges that contact the pin.
