Job Description


The automotive industry is at the forefront of simulation technique and methodology in virtual development, yet it is constantly striving to improve. As the industry has moved towards a more simulation-driven design process the demands for simulation accuracy have increased.
Bolted joints are an integral part in the construction of heavy-duty trucks and buses. The behaviour and failure criterion of these joints are of significant importance when considering crash worthiness and road safety. The aim of this thesis is to perform, and evaluate the results of, fundamental destructive testing of bolts as well as further develop current modelling methodology for bolts used at Scania through the use of explicit FE simulations.
This thesis is a collaboration between AFRY and Scania where the problem formulation is delivered by Scania and the supervision is delivered by AFRY. The thesis student will develop new simulation methodologies and increase the overall knowledge that can pave the way for new modelling guidelines, calibrated against testing data. The result of this work is of great interest for Scania’s future development of safe vehicles and simulation accuracy in general.
Proposed execution:
· Literature study regarding FE-modelling and understanding of material failure models in explicit FE simulations.
· Setup of physical bolt testing and analysis of testing data.
· Assess adequate FE-modelling techniques and useful limitations.
· Perform dynamic simulations of the testing setup and correlate the models to the test data.
· Suggest improvements upon current bolt modelling techniques.
