To characterize delamination in mixed mode I and II, we chose the MMF test which is very practical to deploy because it uses the same assembly and the same test specimen as those of the ELS test. The sound side of the specimen is embedded while the side containing the artificial defect is loaded in the direction of thickness.

To characterize the delamination’s propagation of Ceiba and Birch plywood panels, we used the energy approach which considers that the propagation of the crack chouuaf a phenomenon of energy dissipation.

To determine this parameter, we considered various experimental tests.

Then, we realised a comparative study between the delamination behavior of these two wood species. For each of the specimens, a thin film of Teflon was inserted in the middle plane, thus creating a pre-delaminated zone which will serve to initiate the delamination.

The width of the insert varies according to the type of the specimens. The DCB test consists in propagating a crack within a bonded joint under stress and in measuring the resistance of this joint to the propagation of this crack.

The purpose of the ELS test is to characterize shear delamination of composite materials. This test is characterized by its stability of the delamination propagation when compared to the three-point bending test. The sound side of the specimen is embedded while the side containing the artificial defect is loaded in the direction of thickness.

To characterize delamination in mixed mode I and II, we chose the MMF test which is very practical to deploy because it uses the same assembly and the same test specimen as those of the ELS test. The loading is modified in order to impose a bending in a single lip of the delaminated part of the specimen. From these experimental results, the rate of critical energy restitution Gc can be determined by the experimental complacency method after carrying out the characterization tests of the test specimens.

Chhouaf these values are known, it will then be possible to predict and anticipate the delamination of the plywood. The delamination length is measured by visual observation using a video camera which allows the delamination to be tracked from the beginning to the end of the propagation, the beginning of the propagation being defined as a small propagation of about 1 mm from a pre-cracking.
