A constitutive model considering post-liquefaction deformation based on the logarithmic skeleton curve

open access: yesRock and Soil Mechanics, 2021
Most of the constitutive model for liquefaction analysis cannot simulate the large post-liquefaction deformation of saturated sand, and there is little research on the nonlinear time-domain large deformation constitutive relationships suitable for ...

Comparison of the Warm Deformation Constitutive Model of GH4169 Alloy Based on Neural Network and the Arrhenius Model

open access: yesMetals, 2022
In order to realize a better description of plastic flow behavior in the warm deformation process of GH4149, the GH4169 superalloy was compressed by Gleeble-3800 at a temperature of 700–900 °C and a strain rate of 0.01–10 s−1.

Material Model of Membrane Structure in Rainstorm

open access: yesShanghai Jiaotong Daxue xuebao, 2023
When encountering heavy rain, the membrane surface with a relatively small slope is easy to accumulate water. Accurately simulating the deformation of the membrane surface at this time will help ensure the safety of the structure. The linear constitutive

Application of a damage constitutive model to pile–slope stability analysis

open access: yesFrontiers in Materials, 2022
Piles were regarded as elastic materials in the traditional numerical simulation. The elastic pile would not reflect the damage of the pile in engineering, which would misjudge the reinforcement effect of piles on slopes.
