Fatigue Microcracking of Composite Material IM7/977-2
… IM7/977-2 cross-ply laminates. Using a modified Paris Law approach, microcracking fatigue data is presented over a wide range of applied cyclic stresses. This Paris Law plot shows an "A" value of 6.40x10-25 and a "B" value of 8.07 and provides a complete characterization of composite IM7/977-2 …

Face Sheet/core Debonding In Sandwich Composites Under Static And Fatigue Loading
… which can be exacerbated due to the presence of flaws. In this research work The primary objective of this research was to characterize the delamination crack growth behavior in E-glass face sheet/polyurethane foam core sandwich composite with pre-existing initial delamination crack at a face …

Fracture behavior of CPM 10V
… the hardness. Fatigue crack growth followed the Paris Law for some portion of the curve and crack growth exponents, n, were virtually unchanged by the heat treatment. The linear portion of the growth curve was shifted to higher stress intensity ranges for heat treatments yielding higher fracture …

Stress rupture of unidirectional polymer matrix composites in bending at elevated temperatures
… and last models, respectively based upon a Paris Law and energy considerations relate the time-to-failure to the propagation of the main microbuckle. For this last model, a good correlation between experimental and theoretical data has been obtained. Finally the influence of the temperature …

Piezo-induced fatigue of solder joints
… growth rate approximately corresponded to a Paris law at higher applied voltages. At lower voltages, a strong dependence on frequency was observed, and there was evidence of a threshold strain-energy release rate. Crack growth rates increased with increasing temperature over the range 0- …

Fatigue life prediction on nickel base superalloys
… information from the initiating pores. A Paris law approach is used in conjunction with long crack propagation data. The model shows a good fit with experimental data and further improvements have been recommended in order to increase the capability of the model.

Correlation of localised thermal shock to isothermal biaxial crack growth rates in thin plates of AISI 316 stainless steel.
… thermal stress calculated. From this a modified Paris law is proposed to predict two sets of crack growth rates; one at equibiaxial conditions and the second at a biaxiality determined from the thermal shock load. This is shown to be a minimum of 0.35 at maximum localisation. This will calculate …

Understanding the correlation between wrinkle morphology, fracture and fatigue of plain woven CFRP laminates through mechanical and ultrasonic characterization.
… accelerated crack growth rates and increased Paris law slopes for high-amplitude wrinkles, indicating reduced long-term durability. Furthermore, wider wrinkle spacing disrupted stress continuity, resulting in stepwise, staircase-like crack paths. To support this experimental work, the final …

Modeling reflective cracking development in hot-mix asphalt overlays and quantification of control techniques
… by the number of load repetitions based on the Paris law. A reflective cracking control factor was defined as the ratio of the service life to the HMA overlay without an interlayer system; the factor was used to evaluate the performance effectiveness of these interlayer systems in controlling …
