“…In addition, the choice and the computation method of the modulus may impact the results. Indeed, as reported in Momeni et al (2015), the secant modulus reproduces the three-stage behaviour observed during fatigue experiments while tangent modulus only provides a scattered decreasing trend.…”

“…The different crack processes identified as well as wear along crack edge tend to prove that one or several particular fatigue mechanisms exist. It is particularly shown in Singh (1989) and Momeni et al (2015) that fatigue life is modified by the cyclic amplitude, for a given maximum stress. This is also consistent with the conceptual model presented before, describing the behaviour of a single crack (Zoback and Byerlee 1975;David et al 2012).…”

“…Increasing frequency is shown to increase the number of cycles to failure (Attewell and Farmer 1973;Tien et al 1990;Ma et al 2013;Momeni et al 2015). Indeed, rock strength is inherently strain rate dependent (Zhang et al 2000;Brantut et al 2014).…”

In order to investigate the mechanical behavior of shale rock under cyclic loading and unloading condition, two kinds of incremental cyclic loading tests were conducted. Based on the result of the short-term uniaxial incremental cyclic loading test, the permanent residual strain, modulus, and damage evolution were analyzed firstly. Results showed that the relationship between the residual strains and the cycle number can be expressed by an exponential function. e deformation modulus E 50 and elastic modulus E S first increased and then decreased with the peak stress under the loading condition, and both of them increased approximately linearly with the peak stress under the unloading condition. On the basis of the energy dissipation, the damage variables showed an exponential increasing with the strain at peak stress. e creep behavior of the shale rock was also analyzed. Results showed that there are obvious instantaneous strain, decay creep, and steady creep under each stress level and the specimen appears the accelerated creep stage under the 4th stress of 51.16 MPa. Based on the characteristics of the Burgers creep model, a viscoelastic-plastic creep model was proposed through viscoplastic mechanics, which agrees very well with the experimental results and can better describe the creep behavior of shale rock better than the Burgers creep model. Results can provide some mechanics reference evidence for shale gas development.

This study explored the dynamic behaviors and fracturing mechanisms of flawed granite under split‐Hopkinson pressure bar testing, focusing on factors like grain size and flaw dimensions. By means of digital image processing and the discrete element method, Particle Flow Code 2D (PFC2D) models were constructed based on real granite samples, effectively overcoming the limitations of prior studies that mainly relied on randomized parameters. The results illustrate that the crack distribution of granite is significantly influenced by grain size and flaw dimensions. Tension cracks predominate and mineral boundaries, such as between feldspar and quartz, become primary crack sites. Both flaw length and width critically affect the crack density, distribution, and dynamic strength of granite. Specifically, dynamic strength tends to decrease with the enlargement of flaws and increase with an increase in flaw angles up to 90°.
