which speaks to the learning ability of CNN to learn complex behaviors just from the microstructure. In addition, our CNN's ability to predict modulus, strength, and toughness values derived from stress-strain curves is significantly improved over our previous work [30], which directly predicted ...
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’...
A preliminary investigation of a static pull test using static INSTRON 33R 424 was conducted on six HDPE specimens to validate the material properties, Young’s modulus of 125 MPa, Poisson’s ratio of 0.42 and stress and strain curve. Two HDPE materials of 2 mm thickness with different ...
where ℎ𝛼𝛽hαβ is the slip-plan hardening modulus. Furthermore, Hutchinson proposed that the modulus can be calculated as follows [28]: ℎ𝛼𝛽(𝛾)=ℎ(𝛾)[𝑞+(1−𝑞)𝛿𝛼𝛽]hαβ(γ)=h(γ)[q+(1−q)δαβ] (11) where q is a constant and ℎ(...
aAlthough the method is certainly not exact, unless there is a significant difference, say by a factor of five times or more in the stress-strain modulus of the two materials, more refined computation will improve the computed stress increase very little [see Morgan and Gerrard (1971)]. 虽然...
whereEis the Young’s modulus. The large piezoresistive effects in semiconductors demanded a fundamental theory of the physics. Strain in a crystalline solid modifies the lattice constants and reduces the crystal symmetry, leading to significant shifts in the energy band edges [62]. The existing the...
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....
Additionally, its piezoresistive property [26,27] together with its exceptional physical, electrical [28] and mechanical properties (Young’s modulus on the order of 1 TPa) [29] render graphene an ideal candidate for strain sensors [30]. To date, there have been multiple studies which have ...
Its terms are computed as a function of the Young’s moduli E 1 , E 2 ; Poisson’s ratio ν 12 ; and shear modulus G 12 of the orthotropic medium [1]. The constitutive law (16) takes into account the strain gradient effect. Analogously, a similar relation can be written for the ...
where ρ0c02 is equivalent to the elastic bulk modulus at small nominal strains. There is a limiting compression given by the denominator of this form of the equation of state 𝜂𝑙𝑖𝑚=1𝑠ηlim=1s (8) or 𝜌𝑙𝑖𝑚=𝑠𝜌0𝑠−1ρlim=sρ0s−1 (9) At this...
