The ContourIntegral object defines contour integral objects on an region. Currently only assembly regions are supported.
The ContourIntegral object is derived from the Crack object.
import part mdb.models[name].parts[name].engineeringFeatures.cracks[name] import assembly mdb.models[name].rootAssembly.engineeringFeatures.cracks[name]
This method creates a ContourIntegral object. Although the constructor is available both for parts and for the assembly, ContourIntegral objects are currently supported only under the assembly.
mdb.models[name].parts[name].engineeringFeatures.ContourIntegral mdb.models[name].rootAssembly.engineeringFeatures.ContourIntegral
Required arguments
A String specifying the repository key.
A RegionArray object specifying the crack-front region to which the contour integral is applied. If the crack-front consists of a single region, a Region object may be specified instead of a sequence with a single item in it.
A RegionArray object specifying the crack-tip region to which the contour integral is applied. If the crack-tip consists of a single region, a Region object may be specified instead of a sequence with a single item in it.
A SymbolicConstant specifying how the virtual crack extension direction vectors are defined. Possible values are CRACK_NORMAL and Q_VECTORS.
Optional arguments
A Boolean specifying whether the crack is defined on a half model (about a symmetry plane) or whether it is defined on the whole model. The default value is OFF.
A Boolean specifying whether the regions specified by crackFront and crackTip are specified using a single region or tuples of region objects. The default value is OFF.
A String specifying the name of the crack-front region generated from the tuple of regions specifying the crack-front region. This argument is valid only when listOfRegions is ON. The default value is name+“Front.”
A String specifying the name of the crack-tip region generated from the tuple of regions specifying the crack-tip region. This parameter is valid only when listOfRegions=ON. The default value is name+“Tip.”
A sequence of sequences of Floats specifying the two points of the vector that describes the crack normal direction. Each point is defined by a tuple of two or three coordinates indicating its position. This argument is required only when extensionDirectionMethod=CRACK_NORMAL. The default value is an empty sequence.
A sequence of sequences of sequences of Floats specifying the vectors that indicate the set of crack extension directions. Each vector is described by a tuple of two points, and each point is described by a tuple of two or three coordinates indicating its position. This argument is required only when extensionDirectionMethod=Q_VECTORS. The default value is an empty sequence.
A Float specifying the position of the midside node along the edges of the second-order elements that radiate from the crack tip. Possible values are 0.0
midNodeParameter
A SymbolicConstant specifying the crack-tip singularity. Possible values are NONE, SINGLE_NODE, and DUPLICATE_NODES. The default value is NONE.
Return value
A ContourIntegral object.
Exceptions
This method modifies the ContourIntegral object.
Required arguments
Optional arguments
The optional arguments to setValues are the same as the arguments to the ContourIntegral method, except for the name argument.
Return value
Exceptions
The ContourIntegral object has members with the same names and descriptions as the arguments to the ContourIntegral method.
In addition, the ContourIntegral object has the following member:
A Boolean specifying whether the crack is suppressed or not. The default value is OFF.
