`Defect`¶

class guwlib.guw_objects.Defect(position_x, position_y)¶

Base class to represent plate defects.

Parameters:

position_x (float) – Position of the defect in x-direction from the coordinate origin.
position_y (float) – Position of the defect in y-direction from the coordinate origin.

Variables:

position_x (float) – Position of the defect in x-direction from the coordinate origin.
position_y (float) – Position of the defect in y-direction from the coordinate origin.
id (int) – Unique identification number of the defect.
bounding_box_cell_set_name (str) – Unique name for the ABAQUS cell set of the defects bounding box.

Methods:

set_identifiers(unique_id)¶

Sets a unique ID and ABAQUS cell set name for this defects’ bounding box.

class guwlib.guw_objects.Hole(position_x, position_y, diameter)¶

Represents a simple, circular through-thickness hole.

Parameters:

position_x (float) – Position of the hole in x-direction from the coordinate origin.
position_y (float) – Position of the hole in y-direction from the coordinate origin.
diameter (float) – Diameter of the hole.

Variables:

radius (float) – Radius of the hole.

class guwlib.guw_objects.Crack(position_x, position_y, length, angle_degrees=0)¶

Represents a simple, through-thickness crack (realised by node-separation in the FE model).

The crack is oriented along the y-axis if angle_degrees is set to 0 (default).

Parameters:

position_x (float) – Position of the crack midpoint in x-direction from the coordinate origin.
position_y (float) – Position of the crack midpoint in y-direction from the coordinate origin.
length (float) – Length of the crack.
angle_degrees (float) – Rotation angle of the crack, in degrees (counterclockwise rotation).

Variables:

length (float) – Length of the crack.
angle (float) – Rotation angle of the crack, in radians (counterclockwise rotation).
seam_face_set_name (str) – Name for the ABAQUS face set containing the crack edge faces.
