| Summary: | This project aims to analyse the interactions between a circular inclusion and an interfacial crack
within a bi-material plate of negligible thickness. This study will be utilizing the mathematical
technique of Boundary Element Method to compute the stress intensity factor of the crack tips by
the means of the Multidomain BEM to divide the region of interest into multiple sub-regions, and
the Quarter Point Element to allow for accurate analyse at the crack tip. The parameters that will
be explored are the dimensionless distance between the interfacial crack and the centre of circular
inclusion, the angle of the distance, as well the various combination of stiffness between the three
materials. The conclusion includes how the parameters can be manipulated to induce either an
enhancement or shielding effect on the stress intensity factor of the interfacial crack. |
