Master Graduation Assignment: Thermo-mechanical Fatigue Modeling of Vermicular Cast Iron

Master Graduation Assignment: Thermo-mechanical Fatigue Modeling of Vermicular Cast Iron

Developing advanced thermo-mechanical fatigue (TMF) modeling technique for the cylinder head of heavy duty engines

Functiebeschrijving

The CAE-engines department is responsible for creation and validation of models that can describe and predict the behavior of the new and current engines. Due to increasing requirements on emissions modern diesel engines have become complex systems.
We are seeking a motivated and talented master’s student to join our CAE team to work on an advanced thermo-mechanical fatigue (TMF) modeling project. The goal of this project is to improve our prediction capability of TMF life for our engine components. This is a unique opportunity to gain hands-on experience in a leading engine development environment, working alongside experienced engineers.

Key Responsibilities:

1. Literature Survey: Conduct a comprehensive literature review of current modeling techniques used for predicting thermo-mechanical fatigue (TMF). Include an analysis of modeling techniques for determining the material behavior of vermicular cast irons. Summarize findings and identify potential techniques that could be applied to our specific needs.
2. Technique Evaluation: Assess and compare different TMF modeling techniques to determine the most suitable approach.
3. Implementation and Calibration: Integrate the chosen TMF modeling technique into our existing finite element analysis (FEA) package and post-processor. Calibrate the model to the existing material data.
4. Validation: Validate the TMF model by simulating engine tests performed at DAF. Analyze the simulation results and compare them with experimental data to verify the model’s predictive capability.
5. Presentation of Findings: Compile and present the findings of the project to the engine development team. Prepare technical reports and documentation as required.

Jouw profiel

We are looking to an enthusiastic master’s student:

• Currently enrolled in a Master’s program in Mechanical Engineering, Materials Science, or a related field.
• Knowledge of finite element analysis (FEA) and material modeling.
• Proficiency in FEA software (e.g. Abaqus) and programming languages (e.g., Python, MATLAB) is considered a plus.
• Stronge analytical, problem-solving, and communication skills.
