Fracture Mechanics Analysis Comparison Using Abaqus Progressive Damage and 3-D Crack Meshes of a Downhole Tool

Thursday, May 1, 2025 | 1:45 – 2:15 PM EDT  | SIMULIA Americas Users Conference

Greg Thorwald, Ph.D, Principal Engineer, Advanced Engineering, Daniel Blanks, Senior Integrity Engineer, Advanced Egineering with Quest Integrity and  Shawn Gunter, Senior Engineering & Technology Manager, Technical Support & Management, Disciplinary Science & Engineering with Baker Hughes recently presented at the 2025 SIMULIA Americas Users Conference held at Novi, Michigan.

The presentation analyzed a downhole tool designed to fracture during deployment, demonstrating that the fracture occurs as intended.

The tool features an actuator that applies axial force, causing a cone to slide into a sleeve and generate radial expansion, leading to sleeve fracture. Results from Abaqus reveal the peak fracture force and the sustained force required for deployment.

Two analysis methods were employed: (1) cohesive element progressive damage for fracture growth and (2) focused crack meshes to calculate the J-integral and stress intensity factor K. The commands for creating these models will be reviewed along with a comparison of their results.
