Inertia. You can define lumped mass, rotary
inertia, and heat capacitance at a point on an assembly. In an
Abaqus/Standard
analysis you can also define mass and inertia proportional damping and
composite damping. For more information, see
Inertia.
-
Crack. You can study the initiation and propagation
of cracks using the following techniques:
-
An embedded seam crack with duplicate overlapping nodes
-
A contour integral analysis
-
The extended finite element method
(XFEM)
-
The virtual crack closing technique
(VCCT)
-
Springs/Dashpots. You can define springs and
dashpots that exhibit the same linear behavior independent of field variables.
You can also define both spring and dashpot behavior on the same set of points.
In an
Abaqus/Explicit
or an
Abaqus/Standard
analysis, you can model springs and dashpots that connect two points, following
the line of action between the two points. In an
Abaqus/Standard
analysis, you can also model springs and dashpots that connect two points,
acting in a fixed direction, or that connect points to ground. For more
information, see
Springs and dashpots.
-
Fasteners. You can model point-to-point connections
between two or more faces using point-based or discrete fasteners. Point-based
fasteners can be defined using attachment points, reference points, or orphan
nodes. Discrete fasteners can be defined using attachment lines. For more
information, see
Fasteners.
