The project will deal with a prediction of the bearing capacity of a timber beam with respect to crack initiation and growth that occurs due to presence of notches. Findings of the project are important for both research dealing with theoretical models and following and more applied fields such as civil engineering since both have missing gaps in this knowledge.<\/p>\n
The key research questions of the project are:<\/p>\n
(i) is it possible to use strain energy release rate obtained on small scale samples in real beams?<\/p>\n
(ii) how is the fracture phenomena in timber beams influence by orientation of tree rings?<\/p>\n
