How to obtain the properties for geological faults (considering damage zone and damage core) in numerical simulations?5 answersTo obtain properties for geological faults, including the damage zone and core, in numerical simulations, various methods have been proposed. One approach involves estimating deformation intensity in damage zones, calculating representative values within cell domains, and determining equivalent permeability in cells with oblique deformation bands. Another method includes implementing fault cores as transmissibility multipliers and modifying grid permeability in cells adjacent to faults to account for damage zones. Additionally, a new conceptual model considers fault cores and damage zones as lower-dimensional structures embedded in the rock matrix, enhancing the accuracy of simulation outcomes. Analog modeling studies have shown that fault damage zones evolve non-linearly with displacement, transitioning towards a threshold thickness influenced by fault segment linkage and lithology.
What are the current approaches to model rate dependent fracture response of polymers via the phase field method?5 answersCurrent approaches to model rate dependent fracture response of polymers via the phase field method involve the use of explicit phase field material point methods (ex-PFMPM). These methods discretize the rate-dependent phase field governing equation using a set of particles and update the phase field using explicit forward-difference time integration. The stability of ex-PFMPM is studied, and a critical time step formula is obtained based on system eigenvalues, which considers particle position and neighboring cell interaction. Another approach involves the development of a phase-field fracture model that considers the orientation-dependent fracture of fiber-reinforced polymer matrix composites (PMC). This model captures the damage mechanisms such as matrix cracking and fiber pullout/breakage and can predict the direction-dependent damage propagation and load-deformation response at fracture. Additionally, a model that combines shear yielding, crazing, and void formation is proposed, which considers both ductile and brittle failure simultaneously. These approaches provide physically motivated and computationally tractable frameworks for modeling the fracture response of polymers.
How calculate the crack density?5 answersCrack density can be calculated using different parameters and methods. One approach is to use the crack energy density (CED) parameter, which is defined throughout the life of a crack and can describe various crack behaviors. The CED can be determined independently of the coordinate system and plane on which the integral path is set. It can also be expressed as mode I and mode II contributions, which can be represented by domain integrals without any restrictions on the constitutive equation. Another method is to evaluate the crack energy density from load-displacement curves. The growth rate of a crack can be determined by the increment of crack energy density per one cycle and the gradient of the distribution of crack energy density. These approaches provide valuable insights into understanding crack density and its implications in various fields such as forensic science, medical diagnosis, and creep crack analysis.
How to calculate the crack density in rock?5 answersThe crack density in rock can be calculated using various methods. One approach is to use elastic wave velocities to determine the crack density. The Biot-Gassmann model, which includes elastic moduli and Poisson's ratio, can be used to predict the crack density of rocks. Another method involves measuring the S wave speed, P wave speed, and specific resistance of the rock-bed using elastic wave tomography and specific resistance tomography, and then calculating the crack density based on predetermined relations. Additionally, the crack density can be described using a theoretical model based on the thermodynamic balance law, and the evolution equation of crack density can be derived. Analytic expressions can also be derived for crack density tensor components using effective medium theory and anisotropic poroelastic theory. Finally, crack densities can be compared with in situ shear stress variation to study the relationship between stress state and rock material properties.

How does thermal stress affect the stability and longevity of brittle stars?
4 answers
Thermal stress significantly impacts the behavior and longevity of brittle stars like Ophiocoma erinaceus. When exposed to elevated temperatures, brittle stars exhibit decreased activity levels, with burrowing being a common response at 33°C. Additionally, respiration rates decrease at higher temperatures, indicating a stress response to heat. The mechanical reliability of materials, such as BaTiO3 multilayer capacitors, is also affected by thermal stress, with corner flaws reducing survival probabilities significantly. Studies on quasistatic deformation and fracture of brittle materials under rapidly varying temperature fields show that crack propagation becomes unstable under certain thermomechanical loading conditions, leading to instantaneous crack growth to critical sizes. Thermal stresses, as studied in the stability of cracks under tension, can alter critical tension stresses and affect the stability of cracks in brittle materials.

How does the relationship between bounce rate and loading speed work?
4 answers
The relationship between bounce rate and loading speed varies depending on the material being studied. For sedimentary, igneous, and metamorphic rocks, experiments show that dynamic crack initiation and growth toughness increase with higher loading rates and crack speeds. In the case of limestone samples, an increase in dynamic loading rate leads to higher fracture velocities, indicating a direct relationship between loading rate and fracture velocity. When studying cellular mechanical properties, it was found that the stress-relaxation curves of single cells are not affected by the loading rate of an atomic force microscope above a certain threshold, allowing for more accurate extraction of viscoelasticity parameters. Additionally, at high temperatures, the loading rate sensitivity of SiC microstructures is influenced by a viscous metallic Si phase, with fracture toughness data needing to be determined as a function of loading rate to account for viscous reactions.
