MEC-E8007 - Fracture Mechanics D, Lecture, 23.4.2024-7.6.2024

Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.

LEARNING OUTCOMES

After the course, the student will be able to:

  • understand the theoretical background of linear and non-linear fracture mechanics.
  • apply the principles of fracture mechanics to solve design problems.
  • determine if crack growth will be stable or unstable.
  • define and discuss the most common fracture mechanisms.

CONTENT, ASSESSMENT AND WORKLOAD

Content

  • valid for whole curriculum period:

    The course will start by introducing the fundamental principles of Linear Elastic Fracture Mechanics (LEFM).  This will cover both the energy balance and stress analysis of cracks as well as the necessary conditions for stable crack growth and small-scale yielding.  Then, these principles will be extended to elastic-plastic fracture mechanics by introducing the J-integral.  Finally, the course will provide an introduction to the fracture mechanisms and testing methods applicable for different materials.

  • applies in this implementation

    Should know: Using the stress intensity factor to solve engineering problems; Derive the energy release rate; Predict if crack growth will be stable or unstable; Evaluate the amount of stable crack growth using a R-curve; Calculate the contribution to each mode in a mixed-mode loading scenario; Predict the angle of crack propagation under mixed-mode; Evaluate the size of the plastic zone.

    Nice to know: Calculate the J-integral analytically; Testing methods; Fracture mechanisms; numerical methods related to fracture mechanics.
