Abstract: | We consider a two dimensional elastic isotropic body
with a curvilinear crack. The formula for the derivative of the
energy functional with
respect to the crack length is discussed. It is
proved that this derivative is independent of the crack path
provided that we consider quite smooth crack propagation shapes.
An estimate for the derivative of the energy functional being
uniform with respect to the crack
propagation shape is derived. |
