“…In these graphs, three stages of cracking are easily noticed: the first and second stages are commonly observed [42] which are defined as the "initiation" phase (where the crack length does not exceed 4 mm) and "stable propagation" phase, respectively. The third stage is defined as "fast propagation" corresponding to a growth acceleration after crack length exceeds approximately 9 mm.…”

“…According to Vasiukov et al , damage mechanism can considered to be a non‐linear function of a number of cycles. If samples are free of stress concentrations , then damage growth is fast at the beginning and at the end of the cyclic loading. However, in the middle of the phase, damage propagation is linear in nature .…”

Composite materials have emerged as an effective substitute for conventional materials in various fields of engineering and structural science. For replacement of regular metals, composites, especially fiber‐reinforced polymer composites, have proved to be a suitable alternative. One of the important tests that conventional and composite materials have to undergo is fatigue test. It refers to the testing of materials for their cyclic behavior. In fatigue testing, depending on the choice of the researchers, materials are loaded till reaching their failure or till reaching a fraction of the total stiffness loss. Composite materials are different from metals and they show a distinct behavior under fatigue loading. In metals, failure occurs from the commencement of a single crack and then its propagation. In composite materials, conversely, it is a complex process as these materials possess crack‐arresting properties. This review paper highlights various aspects of the cyclic or fatigue behavior in composite materials. Factors triggering such behavior in composite materials include reinforcing substance, matrix material, fiber orientation or stacking sequence, fiber content, testing environment and so on, together with the damage development process at the microscopic level. Loading condition parameters pertain to stress ratio, mean stress, loading condition, multiaxial stress, and testing frequency. This article also includes the effect of carbon nanotubes on the fatigue life of the polymer composites. POLYM. COMPOS., 39:1785–1808, 2018. © 2016 Society of Plastics Engineers

“…The rotor blades bore complex stresses, which mainly consisted of the bending stress, the distorting stress, the centrifugal force, and the gravitational force [12,13]. The foatn core, whose principal functions are shape tiiaintenance and load transfer, is not the primary loadbearitig part but it bears a partial shear load as well [14].…”

In the periodic inspection of a helicopter flown from 350 to 650 hours, several composite rotor blades were deformed in the body section (between 0.6-0.8 relative radius). The results of blade dissection and damage morphology observation showed that the foam core had been cracked and fragmented. Cracks initiated in the areas near the interface between the loam core and the adhesive film and propagated along the blade body. In the uncrushed foam, some longitudinal cracks were present which penetrated the whole foam core. In addition to dissection analysis, deformation causes were obtained through analyses of the structural design, processing, foam core material properties test, and pull-out test. It was concluded that the immediate cause of rotor blade deformation was foam cracking near the interface induced hy its lower overall properties and poor processing stability, unrelated to structural design and processing. Instead, isocyanate, a component of foam core manufacturing, absorbs moisture, inducing foam properties that are the root cause of rotor blade deformation.
