Energy Principle in Crack Propagation
Fracture mechanics is an engineering discipline, which originated from Griffith energy-balance concept. The energy method is the most powerful analytical tool for fracture mechanics. Starting from energy principle in crack propagation, quasi-static governing equations and energy release rate of DCB specimen can be derived by energy principle in this paper. Finally, some correlative problems are discussed.
