An analysis of the damage is related to the different cutting speeds and feed rates used, as well as the influence of the composition of the material in the delamination factor. A new mathematical model is proposed to characterize the delamination, which is performed in a simple way and considers the damaged area in the delamination factor.

The progression of damage in composite laminates is influenced by the interactions of several failure/damage mechanisms including matrix cracking, fibre breakage, splitting and delamination.
In capturing detailed prediction of various damage modes, it is important to maintain the efficiency of the computational models so that they can be readily used by engineers for damage tolerant design of Cited by: 3.

Klaus Drechsler (TUM LCC) Managing. A simple analysis method based upon a transverse shear deformation theory and a sublaminate approach is utilized to analyze a mixed-mode edge delamination specimen. The analysis provides closed form expressions for the interlaminar shear stresses ahead of the crack, the total energy release rate, and the energy release rate components.
