String instruments makers introduce prestresses on soundboards by adjusting the contact between the strings and the soundboard (downbearing). The effects of these prestresses on the vibration of the soundboard are investigated analytically, using a s

One theoretically studies crack kinking from an ordinary crack (in some homogeneous solid) or an interface crack (between two dissimilar materials), in the situation where this crack is closed prior to kinking but open after it. This problem was rece

It is experimentally well-known that a crack loaded in mode I+III propagates through formation of discrete fracture facets inclined at a certain tilt angle on the original crack plane, depending on the ratio of the mode III to mode I initial stress i

The authors recently theoretically studied crack kinking and opening from an initially closed crack (without friction) in some homogeneous medium. The same problem, but for an interface crack, is considered here. Comninou has shown that the asymptoti

The propagation of fatigue cracks in mode II often leads to the development of a branch starting from a crack flank, some distance behind the tip and not to the expected bifurcation at the crack tip. This type of branch is suggested to initiate by de

Crack kinking in elastic solids in two-dimensional situations is studied in the case where the crack is initially closed (without friction) due to compressive forces but kinking opens it. The first problem which arises, namely the determination of th

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 definiti

One studies crack kinking from an interface crack when this crack is closed prior to kinking but open after it. Contact is assumed to occur without friction. This problem was considered very recently by the authors in the special case of some homogen
