PhD Position Fatigue Crack Initiation and Propagation in Complex Bonded Steel-Composite Joints

Updated: 4 months ago
Deadline: 15 Feb 2024

Predict the fatigue crack growth in composite material and bonded interface by testing and modelling cyclic load behaviour of complex steel-composite bonded joints under multi-axial loading.

Your role in the project/team will be to investigate fatigue crack initiation and growth in the composite material and steel-composite bonded interface of wrapped composite joints. You will focus on:

  • Fatigue (component) testing of steel-composite bonded joints under uni-axial and multi-axial loads;
  • Progressive damage modelling of composite material (cracking) and bonded interface (delamination) under cyclic loading at constitutive and component level using numerical methods;
  • Validation of fatigue tests by finite element modelling.

The research focus of the department Engineering Structures is placed on the investigation and development of resilient, smart and sustainable structures and infrastructures as well as on the structures for energy transition. Within these main themes research is carried out into the dynamics of structures, mechanics of materials related to e.g. climate change, modelling and design of railway systems, multi-scale modelling of pavement materials and structures, reuse of materials, structures and parts of structures, assessment methods for structures, smart monitoring techniques, design methods, replacement and renovation of civil infrastructure and development of new materials and maintenance techniques. The groups are using the unique Macro Mechanics Laboratory for full scale testing, monitoring and modelling of structures to facilitate implementation of innovations. The department delivers a large number of courses both at the BSc and MSc level.

Background in terms of BSc and MSc in field of (combinations possible):

  • Civil/Structural Engineering (e.g. fatigue resistance of steel structures, connections, composites/FRP structures, tubular CHS or RHS joints);
  • Mechanical engineering (e.g ship building, wind turbine blades, offshore structures, fibreglass pipelines);
  • Aerospace Engineering (e.g. composites, fatigue and structural integrity).

Required skills/a candidate should have the following experience:

  • Non-linear FEA for analysis of structural joints and/or components;
  • Failure mode (fracture) and/or fatigue characterisation/analysis of structural components/joints (preferably composite or steel).

Desired skills/ a good candidate would have some of the following experience:

  • Designing of test set-ups, conducting and post-processing of component cyclic and/or monotonic level experiments;
  • Measurement techniques using DIC, LVDTs and optical fibres;
  • Writing and publishing papers at conferences and in scientific journals.

Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate is able to communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis.
