We are delighted to share the success story of Isaak Trajković, who recently completed his Short-Term Scientific Mission (STSM) under the EuMINe COST Action. His research focused on developing a digital twin model to analyze the behavior of pipeline materials under stress. Hosted by Intera Technology Park in Bosnia and Herzegovina, this project has yielded significant advancements in the field of materials informatics.
Work carried out
Isaak’s work during the STSM centered on creating and validating a digital twin model using Simulia Abaqus CAE to replicate ring-shaped test tubes with cracks. The model integrated fracture mechanics and advanced finite element methods (FEM) to simulate crack propagation under various loading conditions. Experimental validation involved rigorous testing and data collection to calibrate the model, ensuring accurate predictions of stress and deformation patterns.
Key Achievements
- Development of Digital Twin Model: Successfully developed a detailed digital twin model of ring-shaped test tubes with one and two cracks.
- Integration of Fracture Mechanics: Applied advanced FEM for precise simulation of crack propagation.
- Experimental Validation: Conducted thorough tests on ring samples, calibrating the model with empirical data.
- Model Optimization: Enhanced the model to predict pipeline material behavior under different conditions, providing critical insights into fracture mechanisms.
These achievements have significantly advanced our understanding of pipeline material behavior under stress, leading to improved testing methodologies and predictive accuracy.
Planned Follow-Up Activities
Isaak plans to publish a comprehensive research paper detailing his methodologies and findings. Additionally, he will present his work at the European Conference of Fracture (ECF), fostering further collaboration and discussion within the scientific community. Isaak Trajković’s STSM has made a substantial contribution to the field of materials informatics, particularly in the predictive modeling of pipeline materials. His work exemplifies the impactful research supported by EuMINe and highlights the potential for future innovations in material safety and reliability.
