Define a Hotspot

Defining a Hotspot to which Crack Properties are assigned.

  1. Click the Hotspot tool.
    Figure 1.
    The Hotspot guidebar opens.
    Figure 2.
  2. Click on the left icon to open the Hotspot creation options.
    Figure 3.
    Creation option is set to Manual.
    Figure 4.
    Note: Custom Config file allows user to creating a hotspot at required node and create-assign a system to define the crack direction. The feature requires a configuration file (.txt) linked to a .csv file containing nodal information for system creation using 3 nodes.
  3. Click on Nodes and select node by ID: 1814 and click on the button to create hotspot at selected node.
  4. Open Crack definition options by pressing the button.
    Figure 5.
    Figure 6.
    1. Set Crack Direction to Normal.
      Note:

      System defining the crack direction can be created and assigned to the hotspot.

      From the created system: Z-axis represent the crack direction and XZ-plane represents the Stress distribution direction.

    2. Set Bias Method to Adapt to Mesh Size.
      Adapt to Mesh Size extracts stress in elements bisecting the crack direction. Biasing Coefficient defines the number of points from each element in the crack direction.
    3. Residual table and Crack Angle are not applied.
      Crack Angle allows rotation of the XZ plane for stress distribution direction.
    4. Crack dimension and Crack type are set to Two Dimensional Crack – WF solutions and Semi-Elliptical surface Crack.
    5. The following crack dimensions are updated.
      • Specimen thickness: 19.0
      • Initial Crack length: 0.05
      • Final Crack Length a: 15.2
      • Initial Crack Length b: 0.1
      • Final Crack Length b: 15.2
      • Max no. of cycles (0=inf): 100000000
    6. Exit the dialog.
