Description
A mode III crack problem in linear elastic fracture mechanics
is a relatively easier problem compared with other type of
modes, for it leads to a very familiar PDE--Laplace's equation,
with a mixed value boundary conditions. In this talk,
fracture mechanics in functionally graded materials (FGMs) will be
introduced. Two elastic models, classical and gradient elasticity
will be briefly addressed and compared.
Mathematical methods will be laid out, with focus of
the method of integral equations. Numerical solution including
the crack profile and stress intensity factors (SIFs) will be
presented. Further application and research work will be discussed.
