    Description

    The design of highly important structural components (such as pressurised containers, machinery parts, transport, energy, and so on) which is normally done using the specific codes applicable in each sector, and which are usually based on criteria of tension and/or stress. Quite often, these elements can suffer cracks due to the actual manufacturing process or incorrect dimensioning, which leads to a need to assess the safety of the components through the use of calculation methods based on fracture mechanics.
    The thesis will focus on the application and/or development of new prediction methods regarding the growth of cracks in metallic structures under cyclical loads. Currently, there are methods based on fracture mechanics, which satisfy, to a greater or lesser extent, the decision-making process when structures or metallic components subjected to cyclical loads show cracks of different size and nature.
    In this area, the thesis aims to identify, apply and develop methods, which allow, once a cracked structure has been identified, to assess:
    (i) the ability of the structure to continue to fulfil its purpose,
    (ii) its remaining useful life,
    (iii) plan inspections to guarantee its operability and
    (iv) determine when and how to perform the necessary repairs on it.
    The current methods, together with that which will be developed during the thesis, will be applied to experimental study cases in order to assess the ability to predict and improve precision in each of the developments made.
