NDE of heat and fatigue damages in CFRP composite laminates.
Several NDE methods for the quantification and the qualification of damages in CFRP structures already exist. In this project we will be interested in acoustic, thermal and optical methods such as acoustic emission (AE), Thermography (TT) and Sherography (ST). The project will be based in a team of 5 engineers and typically requires a mix of experimental and theoretical work
· The first aspect of this project is to perform a thorough bibliographical work on the mode of failure of composite structures submitted to bending and heat and also on previous application of NDE methods to the detection of heat and fatigue damages in composites.
· The second aspect of this project is modelling. Using FEMLAB, composite laminates will be modelled. Later, the equations describing the initiation and the growth of delamination in composite will be computed. The purpose of the models is too enhanced our comprehension of various factors affecting the results of AE, ST and TT experiments.
· The third aspect of this project is experimental. Several NDE experiments will be performed on fatigued and heat affected composite samples in order to obtain quantitative information of the sensitivity of the NDE methods used.
You should be well educated in analytical methods, ideally in solid mechanics, or material science. Good knowledge of the Finite Element Method and MATLAB is required.
You should have a strong interest in performing practical experiments. No particular knowledge in NDE methods is required.
You are confident speaking and writing the English language, as well as the Swedish language.
Period: 20 weeks, starting during summer or august.
