چکیده
|
Repairing a crack in a structure consists in reducing crack rsquo;s tips stresses by transferring loads trough a bridge made of the composite patch and the adhesive. this operation is impacted by four factors: shear modulus of the adhesive, the composite patch rsquo;s young module and the thicknesses of these two materials. the design of experiments method allowed us to determine, the weight of each of the four factors and their interactions as well their best combination to obtain an efficient and lasting repair. the constraints relative to the stiffness ratio and the shear strain were taken into consideration in order to determine the best configuration that allowed the minimization of k.
