Learning outcomes

During the course a participant should acquire experience and become able to:

  • explain the role of solid mechanics modeling and computation in the product development process, in particular in relation to a multitude of failure modes;
  • consider also hidden failure modes in the above mentioned situation;
  • identify mechanical requirements on components and structures and translate them into a mechanical model that is suitable for computations;
  • select appropriate FE-meshes, elements, boundary conditions, material models, etc, for efficient problem solving;
  • describe the purpose and ideas of different design strategies;
  • use advanced methods for FE-based fatigue design (LCF, HCF and TMF);
  • describe different forms of uncertainty and estimate the scatter of stochastic variables;
  • illustrate and explain how uncertainty in a problem spread to uncertainty in the system response;
  • select an appropriate method for exploration of the design space;
  • perform probabilistic design with FEM based on direct Monte Carlo simulation or with a surrogate model (RSM);
  • solve an advanced product development problem and communicate the solution in the form of a poster, an oral presentation and a technical report.

Course main content

The course is based on advanced, higher level, use of solid mechanics theory and modeling. This is added to the already acquired knowledge of the participants. The course is mainly experiential. The course includes a lecture series, including guest lecturers from industry. There are individual design exercises as well as a larger final project to be solved in a small group.

Eligibility

Compulsory courses are SE1010 Strength of materials and solid mechanics basic course, or SE1012 Strength of materials and solid mechanics basic course, or SE1020 Strength of materials and solid mechanics basic course, or SE1055 Strength of materials and solid mechanics basic course, and SE1025 FEM for Engineering Applications.  Recommended courses are SE2132 Applied Elasticity with FEM and SE2126 Material Mechanics.
