In the last decades, the increasing use of laminate materials, such as carbon fibre reinforced plastics, in several engineering applications has pushed researchers to deeply investigate their mechanical behavior, especially in consideration of the delamination process, which could affect their performance. The need for improving the capability of the current instruments in predicting some collapse or strength reduction due to hidden damages leads to the necessity to combine numerical models with experimental campaigns. The validation of the numerical models could give useful information about the mechanical response of the materials, providing predictive data about their lifetime. The purpose of the delamination tests is to collect reliable results by monitoring the delamination growth of the simulated in situ cracking and use them to validate the numerical models. In this work, an experimental campaign was carried out on high performance composite laminates with respect to the delamination mode I; subsequently, a numerical model representative of the experimental setup was built. The ANSYS Workbench Suite was used to simulate the delamination phenomena and modeFRONTIER was applied for the numerical/experimental calibration of the constitutive relationship on the basis of the delamination process, whose mechanism was implemented by means of the cohesive zone material (CZM) model.

“…Turon et al [9,10] presented an accurate analytical solution for delamination growth under mixed-mode loading using cohesive elements. The significant effects of buckling and delamination growth for various parameters (delamination size and distribution) in slender composite laminate were investigated with FEM based on a cohesive element [11,12]. Ataş et al [13][14][15] conducted numerical analysis to study the clamping force effects on the delamination onset and growth: pinned and bolted (protruding head bolts) composite laminates.…”

During countersunk hole machining, defects like geometrical deviation of the chamfer angle and delamination are easily introduced into the structure. To investigate the influences of geometrical deviation on delamination propagation around the countersunk hole during assembly, a progressive damage model (PDM) combining cohesive element was proposed and validated. Numerical analyses were then carried out to study delamination propagation behavior under the influences of geometrical parameters including delamination factor, chamfer angle, and location of delamination. The results show that when delamination appears at the transition area of the countersunk hole, the load causing the delamination evolution is much smaller than other cases.

“…Under monotonic compressive loading, delaminated composites might experience delamination buckling and growth. 14,15 As the delaminated plate undergoes repeated buckling and unloading, a progressive accumulation of damage at the delamination front occurs. [16][17][18] As a consequence, an existing delamination may grow, even if the static growth criterion is not satisfied (i.e.…”

Delamination fatigue growth experiments are carried out on angle ply T700/TDE85 Graphite/Epoxy laminates under compressive fatigue loads. Delamination growth is monitored in real time during fatigue test. Three-dimensional finite element methods are used to calculate strain energy release rate G by standard ABAQUS procedures. Components of strain energy release rate as the delamination grows are discussed. In particular, the delamination growth rate da/dN and the stabilized delamination length are systematically investigated in order to define the effect of loading level, delamination size, and delamination position on delamination growth behavior under compressive fatigue loads. Furthermore, scanning electron microscopy techniques are used to identify the fatigue delamination growth mechanisms and to assess the delamination growth behavior.
