Content, progress and pedagogy of the module

Learning objectives

Knowledge

Students who complete the module:

  • Should have basic knowledge about non-linear effects in structural response, i.e. influence of large displacements, plasticity or other non-linear material behavior and dynamic effects.
  • Should have knowledge about advanced structural analysis and its applications in offshore structures.
  • Should have knowledge about non-linear behavior of thin-walled structures i.e. buckling and postbuckling behavior and influence of geometric imperfections.
  • Should have knowledge of modelling joints in structures linear as well as non-linear.
  • Should have knowledge about non-linear Finite Element analysis of thin-walled structures.

Skills

Students who complete the module:

  • Should be able to formulate a mechanical/mathematical model for offshore structures behaving non-linearly.
  • Should be able to formulate geometrically non-linear models for thin-walled structures involving buckling, postbuckling and imperfection sensitivity. 
  • Should be able to estimate the stability load for simplified thin-walled structures based on analytical models.
  • Should be able to formulate mechanical/mathematical models for joints in structures e.g. flexible joints in frame structures. 
  • Should have sufficient background to choose an appropriate numerical model i.e. type of element and type of non-linear solution algorithm.
  • Should be able to analyze a structure/structural component by a non-linear Finite Element code e.g. push-over analysis of offshore platforms.
  • Should be able to verify the numerical results from Finite Element calculations by analytical models or other simplified models.
  • Should be able to interpret the results from a non-linear Finite Element calculation.

Competences

Students who complete the module:

  • Should be able to participate in non-linear analysis of offshore structures and participate in a dialog on structural modifications in order to improve the structural response.
  • Should be able to model and analyze thin-walled structures with geometric non-linear behavior and participate in a dialog of non-linear analysis of other structures.
