Burgers-type empirical creep model for unsaturated soil considering matric suction

Shenzhen Daxue xuebao. Ligong ban
Reservoir bank slopes are often in an unsaturated state due to water level fluctuations and atmospheric precipitation, which can easily trigger landslides. Therefore, it is necessary to develop a creep model for unsaturated soils that accounts for matric

Dynamical aspects of transient electro-osmotic flow of Burgers' fluid with zeta potential in cylindrical tube

Nonlinear Engineering, 2023
In this article, we consider the flow of a Burgers’ fluid of transient electro-osmotic type in a small tube with a circular cross-section. Analytical results are found for the transient velocity and, electric potential profile by solving the Navier ...

Density Matrix Renormalization for Model Reduction in Nonlinear Dynamics

, 2007
We present a novel approach for model reduction of nonlinear dynamical systems based on proper orthogonal decomposition (POD). Our method, derived from Density Matrix Renormalization Group (DMRG), provides a significant reduction in computational effort ...

Ga Doping Enables Precision Alloy‐to‐Wire Regulation: Synergistic Enhancement of the Mechanical Properties of CuSn Alloy and the Superconducting Properties of Nb3Sn

Advanced Science, EarlyView.
By adjusting Ga's doping in Cu–Sn alloy, an ultra‐high elongation of 100.8% is achieved in first time. Ga forms a stable solid solution structure and a stronger electron exchange with Cu. This enhances strength‐ductility synergistically by tuning SFE to balance twinning and slip.

Fractional generalized Burgers’ fluid flow due to metachronal waves of cilia in an inclined tube

Advances in Mechanical Engineering, 2017
In this study, the cilia-induced flow is discussed for fractional generalized Burgers’ fluid in an inclined tube. The mathematical model of fractional generalized Burgers’ fluid flow is obtained under the long-wavelength approximation.

Models of Passive and Reactive Tracer Motion: an Application of Ito Calculus

, 1997
By means of Ito calculus it is possible to find, in a straight-forward way, the analytical solution to some equations related to the passive tracer transport problem in a velocity field that obeys the multidimensional Burgers equation and to a simple ...

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics

Advanced Science, EarlyView.
The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...

Study on long-term stability of downhill protective coal pillars in deep mines based on Burgers model

Meikuang Anquan
The protective coal pillars in the downhill sections of deep mines are long-term in a complex environment of “three highs and one disturbance”(high stress, high water pressure, high ground temperature and excavation disturbance) , and their cumulative ...

Derivation of the Variants of the Burgers Model Using a Thermodynamic Approach and Appealing to the Concept of Evolving Natural Configurations

Fluids, 2018
Viscoelastic rate-type fluid models involving the stress and frame-indifferent time derivatives of second order, like those in Burgers’ model, are used to describe the complicated response of fluid like materials that are endowed with a complex ...
