What´s in it for you?

In the automotive industry one is continuously making efforts to reduce weight of the car body. For quite some years the trends has been switch from low strength steel to high strength steel. Now the trend is to introduce lighter materials such as aluminum. This implies that there is also a need of suitable joining methods for aluminum, such as e.g. Self Piercing Rivets (SPR). To be able to design a strong, light and stiff car body, we must be confident that the simulations that are performed to support the design work comply with the final physical verification test. Because of this, there is a need for improvement of the modelling, simulation and verification process of different types of joints in aluminums in a complete car body.


The goal of the thesis work

In this work a detailed CAE model of a  self piercing rivet joint is to be modelled, simulated and verified.

• Literature survey on self piercing rivets

• Literature survey on different CAE modelling techniques for self piercing rivets

• Modelling using nonlinear FE analysis

• Process simulation of Self Piercing Rivet

• Followed by simulation of quasi static coupon testing
The goal is to establish a method for virtual testing of Self Piercing Rivets.


The diploma work will include the following elements:
• CAE modelling in Ansa
• Nonlinear FE-analysis in LS-DYNA
• Evaluation and correlation of coupon testing for self piercing rivets

Scope of your work

• Starting date in January 2020
• ECTS (Academic Credits/”Högskolepoäng”) 30 ECT
• For 2 students
• Work will be done at Principal Engineering department, Volvo Car Corporation, Torslanda


Do you fit the profile?

• Mechanical engineering with focus on computational mechanics or similar
• Fluent in English, written and verbal
• Good knowledge and interest of FE-analysis and optimization

We are looking for you who are curious and have the ability to work independently. If you believe this work suits you and you find yourself in the profile, do not hesitate to apply.
