... on dynamic characteristics of the damaged structure. Dimarogonas ( 1 ) has summarized these works into three categories, namely: Continuous model, discrete-continuous model, and discrete models, i.e., finite element models. plates (structures) elastic constants stress effects crack detection...

... crack propagation, and crack detection based on free vibrations. First, we have considered the shear and normal stresses and strains in the adhesive layer to propose an optimization to uniform axial strength (UAS) and to reduce the stress peaks in the bond. The stress analysis confirms that the maximum...
