“…However, his study neglected the effects of contact and friction on the crack extensional characteristics. Other studies on the effects of biaxial loading conditions, including the combined tensile and compressive loading conditions, have been conducted by Liebowitz et al (1978), Theocaris andMichopoulos (1983), Shetty et al (1987), and Zeng and Dai (1994), Shlyannikov (2013), Ge et al (2014), Kannusamy and Ramesh (2014), and Meek and Ainsworth (2015).…”

The brittle fracture of rock with an angled crack under combined tensile and compressive loading conditions is studied using linear elastic fracture mechanics (LEFM). The modified maximum tangential stress criterion (MTSC) and the maximum shear stress criterion (MSSC) are used to check crack initiations in the tensile and shear modes, respectively. The effects of the friction coefficient of the crack surfaces and the nonsingular stresses (T stresses) on the crack initiation are studied for the cases of both low and high compressive confining pressure coefficients. The T stresses include those both parallel (Tx) and perpendicular (Ty) to the crack plane. The type of crack initiation under the combined tensile and compressive loading conditions is found to remain tensile dominated when the compressive confining pressure coefficient is small. However, shear crack extension becomes possible with the compressive confining pressure coefficient and friction coefficient increasing if the crack orientation angle is small. Moreover, the high compressive confining pressure and substantial friction are found to increase the possibility of shear crack extension. The theoretical predictions presented in this study move one step forward than the available analytical solutions for the angled crack subjected to general biaxial load and agree well with those from experimental tests.

“…No obstante, el método no provee una carga tracción-compresión que se ajuste a la respuesta real de la estructura de pavimento. Tras el paso de una carga se genera una gran concentración de tensiones de tracción en la zona inferior de la capa, traducidas en un esfuerzo de compresión en la parte superior; cuando la carga se aleja del punto de medición, las tensiones se revierten de nuevo, lo que genera un estado continuo de tensiones de tracción y compresión en el material [19], [20].…”

La fisuración por fatiga es uno de los mecanismos de deterioro más comunes en las estructuras de pavimentos. Este fenómeno está asociado al deterioro generado como consecuencia de la aplicación de cargas repetitivas cuya magnitud de carga es inferior a la resistencia máxima admisible que puede soportar el material. Por lo mismo, la aplicación continua de las cargas generadas por la acción del tránsito, dan lugar a un progresivo deterioro de las capas del pavimento. En la actualidad, existen distintas metodologías que permiten predecir la fisuración por fatiga, pero un gran número de estas se caracterizan por ser procedimientos complejos, y en muchas ocasiones no se garantizan la falla de algunos tipos de mezclas y/o no relacionan las condiciones de carga aplicadas con las sufridas en el pavimento. Es por esto, que el desarrollo de ensayos efectivos es fundamental para comprender el comportamiento frente a la falla por fatiga de las mezclas asfálticas. En este contexto, el artículo presentado tiene como objetivo principal proponer una metodología de ensayo para evaluar la fisuración por fatiga por medio del uso una probeta cilíndrica entallada. El método propuesto permite la reproducción del estado tensional del pavimento, evitando la disipación de esfuerzos, concentrando las tensiones en la zona intermedia de la probeta, previamente entallada. Para este procedimiento propuesto, se evaluaron tres tipos de áridos para una mezcla semidensa usualmente utilizada en capas de rodadura, determinándose las leyes de fatiga para cada mezcla. Además, se presenta un análisis de durabilidad de las mezclas evaluadas.

“…In the equation m = 2 m/T, T is the distribution period of the sinusoidal load, which was set to be 2L/c in this paper, m is a constant, and c is the loaded driving speed under the actual situation, ranged from -∞ to +∞ (this is applied to (13) and (15)).…”

“…It is well known that many literatures analyzed the traffic load with a fixed location of load application, but a changing load size and half-sinusoidal load functions can better simulate actual traffic loads. Many researchers often replaced the actual traffic load with the impulsive load and input the latter in finite calculation models for the dynamic response of asphalt pavements [9,[13][14][15][16]. However, until now, no researcher has applied the method of analytic solution and analyzed the dynamic response of asphalt pavements under half-sinusoidal, triangular, and vertical stepwise load.…”

This paper establishes the equivalent relationships between the half-sinusoidal load, triangular load, vertical stepwise load, and moving traffic load. The governing equation was established for analyzing the dynamic responses of pavement, and half-sinusoidal load, triangular load, and vertical stepwise load functions were transformed into Fourier series expressions. The partial differential governing equations were simplified as ordinary differential equations and the analytical solutions were obtained. Further, the solutions were validated through comparing the theoretical results with numerical simulated results. Calculation results revealed that, for unchanged load periods, increasing the amplitudes of the three loads by 1.06, 1.31, and 1.35 times can better simulate the moving traffic loads. For unchanged load function amplitudes, increasing the function periods by 1.07, 2.23, and 2.1 times (for half-sinusoidal, triangular, and vertical stepwise loads, resp.) can improve the simulation performance. The fatigue life of asphalt pavements under the moving traffic load agrees with that of the three load simulations, indicating that the fatigue life of asphalt pavements is only associated with the load amplitude but not the load patterns.
