Mixite modale pour une fissure d 'interface
Application a I' essai bresilien
Keywords:
Elasticity, interface, fracture, mixity of modesAbstract
At an interface crack tip, the usual mode I and mode II splitting of the singular stress field is impossible due to a complex exponent, there is a mixity of modes. A direct computation of the complex intensity factor allows to give a precise definition of this mixity. Even if some ambiguities remain, it removes an arbitrary parameter which is the distance where measures or computations must be performed.
