The novel PnC model proposed in this work selects silicone rubber as the matrix material and lead as the columnar scatterer material. The corresponding material parameters of silicone rubber are taken as densityρ = 1300 kg m−3, Young modulusE = 1.175 × 105Pa and Poisson’...
We conducted GDS dynamic triaxial tests to study the change rules of the hysteresis curve morphology, axial strain, dynamic elastic modulus, and damping ratio of waste tire rubber-mixed sand-based subgrade model samples with different rubber particle sizes, rubber mixing amounts, and loading times....
The identification of these four parameters is based on cyclic tests combined with numerical simulation. The evolution of scalar function 𝑔(𝛼)g(α) is calculated according to the formula suggested by Pan and Rice [27]: 𝑔˙(𝛼)(𝛾)=∑𝛽=1𝑛ℎ𝛼𝛽(𝛾)|𝛾˙(𝛽)|,...
effect and valleytronics [33,34,35,36]. Both theoretical predictions and experimental results demonstrated the excellent mechanical properties of 2D materials, such as high elasticity modulus (180 ± 60 N m−1for monolayer MoS2) and Young’s modulus (270 ± 100 GPa for monolayer MoS2...
𝐶2𝐷C2D and 𝐸𝑖Ei are the elastic modulus and deformation potential constant for 2D systems, respectively. Here, C2D = 2(∂2(E − E0)/∂ε2)/S, where S is the cross-sectional area. Herein, the orthorhombic lattice of the GeS2 monolayer was built for the carrier mobility...
This formula, used in combination with (2), makes it possible to calculate an estimation of the yield stress of high-strength steels at any strain rate without performing specific experiments at different strain rates. This same method is extended to the calculation of critically resolved shear st...
The percentage mass distribution of particles and fines increases with increasing bedding orientation. The effect of water on the dynamic damage of coal samples is significant. Based on the principle of pressure expansion of wing-shaped cracks, the formula for calculating the dynamic strength of ...
