Elastoplastic constitutive model for biocemented sands

Yantu gongcheng xuebao, 2022
The microbial-induced calcite precipitation (MICP) is a new method for reinforcing geotechnical materials with environmentally friendly bacteria. The test results show that the stiffness, strength and dilatancy of the MICP-treated sands are enhanced ...

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

Frontiers 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.

Investigation on the Expression Ability of a Developed Constitutive Model for Rocks Based on Statistical Damage Theory

Lithosphere, 2022
The three-parameter Weibull distribution has a strong ability to fit many kinds of experimental data, which provides a solution for using a unified expression to characterize the elastic-brittle, strain softening, elastic-plasticity, and other ...

Constitutive Model of Swelling Gypsum Rock

Advances in Civil Engineering, 2020
Swelling of soft rock, such as gypsum rock, is one of the major threats in tunnel engineering, causing structure damages such as floor heave and inward movement of sidewalls during construction and operation.

Visco-Elastoplastic Constitutive Fatigue Model for Rocks

Advances in Civil Engineering, 2020
The study on the constitutive fatigue model for rocks under cyclic loading has an important significance in rock engineering. In order to study the fatigue properties of rocks under cyclic loading, according to the theory of rheological mechanics and the

Constitutive modeling of dispersive mixtures [PDF]

Journal of Rheology, 2001
A rheological model for the stress in liquid-liquid systems is developed based on unifying the theory of the present phenomenological models and by applying a description of the dispersed phase microstructure to remove most of the adjustable parameters present in the theological models.

Cup‐Like Nuclei Is a Hallmark of DUX4/ERG Acute Lymphoblastic Leukemia and Reveals Cytoplasmic Mitochondria Accumulation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Cup‐like nuclei are a distinctive morphological feature observed in certain cases of acute lymphoblastic leukemia (ALL). We provide evidence that they characterize DUX4/ERG ALL independently of IKZF1 deletion and reveal marked mitochondrial accumulation in this ALL subset.
