Summary: We investigate 2D incompressible inertial flows through porous media and find that the constitutive, nonlinear model can be transformed into a linear one by introducing a new parameter K* encompassing all inertial effects at small scales. For naturally occurring formations at large scales, K* varies erratically, and we analytically compute its counterpart, termed generalized effective conductivity, using the self-consistent approach (SCA). Despite its approximate nature, SCA yields simple results that agree well with Monte Carlo simulations.

Summary: The evolution of pore pressure induced by tunnel excavation in low permeability anisotropic ground was investigated using a fully coupled hydro-mechanical finite element simulation. The study found that overpressures can be induced before the passage of the face, depending on factors such as rock consolidation time, excavation rate, and the degree of anisotropy in the material and initial stress state. Discussions on pore pressure evolution at the tunnel wall and proposing a pore pressure release rate for 2D models were also presented.

Summary: This article proposes a finite-element method for computing flows involving a fluid-hydrogel interface. The hydrogel is treated as a poroelastic material and the interfacial deformation is coupled with the fluid and solid governing equations. Numerical tests show excellent agreement between the results obtained using this method and analytical solutions in various flow problems.

Summary: Researchers studied the permeability of packs of spheres with different sizes and porosities through numerical simulations and fluid flow experiments, finding some patterns. Results were well-fitted with cubic arrays of spheres model at porosities greater than 0.38, and the Kozeny-Carman relationship provided a good approximation for packs of closely packed spheres with low porosities.

Summary: The flow behaviors in created fracture complexity strongly affect the productivity of wells after hydraulic fracturing. Gas flow tests were conducted in both splitting fractures induced by Brazilian splitting and hydraulic fractures created by hydraulic fracturing, and the nonlinear fluid flow behaviors in rough fractures were studied. The results show that splitting fractures have higher transmissivity and are more prone to nonlinearity, while hydraulic fractures have smaller roughness indices and aperture sizes. Therefore, hydraulic fractures should be fully considered for more accurate evaluation in engineering practice.

Summary: This study aims to explore an effective modeling method for biomimetic porous bone scaffolds and evaluate their tissue fluid/nutrient mass transport characteristics. By imitating the histomorphological characteristics of human vertebral cancellous bone, the researchers developed a three-dimensional printing method for porous scaffolds. The results of flow characterization and mechanical testing showed that the porous scaffolds had good permeability and mechanical properties, contributing to cell adhesion and migration. The proposed design method offers adjustable parameters for generating diversified functional porous structures to meet specific needs.

Summary: The linear stability of a plane Poiseuille flow in a channel with anisotropic and inhomogeneous porous layers is analyzed by solving the generalized Darcy and Navier-Stokes equations. The coupling between the flows in the porous and fluid layers is considered using the Beaver-Joseph interface condition. The spectral collocation method is employed to solve the Orr-Sommerfeld eigenvalue problem for disturbances of arbitrary wavenumbers, and the effect of anisotropy and inhomogeneity on stability characteristics is investigated.

Summary: This study overcomes the difficulty of harnessing the flexoelectric effect by designing multiscale metamaterials. Through topology optimization calculations, we obtain optimal structures for various apparent piezoelectric properties and find that low-area-fraction lattices are the preferred choice. The results show competitive estimations of apparent piezoelectricity compared to reference materials such as quartz and PZT ceramics.

Summary: The coexistence of both austenite and martensite is a common characteristic in Shape Memory Alloys (SMAs). The multiple-domain microstructures, consisting of austenite, martensite twins, and individual martensite variants, evolve collectively during the phase transformation, affecting the material's macroscopic response. This paper presents an experimentally observed interface consisting of five domains in a Ni-Mn-Ga single-crystal, and analyzes the effects of thermal loading path and material initial state on the domain pattern formation.

Summary: In this work, the authors investigate the possibility of enhancing the resistance to crack growth in brittle materials through microstructure design. They establish a computational framework to simulate crack propagation and characterize fracture energy. The effects of different types of voids on toughening mechanisms are explored, and the critical conditions for embrittlement-toughening transition are identified. The study also discusses the difference between void toughening in brittle and ductile materials, and extends the toughening strategy to nacre-like materials.

Summary: This study establishes a cytoarchitectural model to accurately capture the buckling and postbuckling behaviors of epithelia under fast compression. The stress evolution of epithelia is divided into three stages: loading, phase transition, and stress recovery. The postbuckling process is governed by the active tension generated by the actomyosin network. The study also proposes a minimal model that predicts the flattening time and stress recovery extent as functions of applied strain or strain rate, in agreement with simulations and experiments.

Summary: Motivated by the extraordinary strength of nacre, this study investigated the probabilistic distribution of fishnet strength using Monte Carlo simulations and found that previous analytical solutions are not applicable for fishnets with a large number of links. By approximating large-scale fishnets as a continuum with cracks or holes, the study revealed that the strength distribution follows the Weibull distribution. This new model has significance for optimizing the strength-weight ratio in printed material structures.

Summary: This paper revisits the mathematical foundations of nonlinear viscoelasticity and studies the geometry of viscoelastic deformations. It discusses the decomposition of the deformation gradient into elastic and viscous distortions and concludes that the viscous distortion can only be a two-point tensor. The governing equations of nonlinear viscoelasticity are derived and the constitutive and kinetic equations for various types of viscoelastic solids are discussed.

Summary: We have developed a simple model that describes the ionic current through neuronal membranes by considering the membrane potential and extracellular ion concentration. The model combines a simplified Poisson-Nernst-Planck model of ion transport through individual ion channels with channel activation functions calibrated from experimental data. The calibrated model accounts for the transport of calcium, sodium, potassium, and chloride and shows remarkable agreement with experimentally measured current-voltage curves for human neural cells.
