All-solid-state batteries (ASSB) can potentially achieve high gravimetric and volumetric energy densities (900 Wh/L) if paired with a lithium metal anode solid electrolyte. However, there is lack in critical understanding about how to operate cells at capacities minimize unwanted degradation mechanisms such as dendrites voids. Herein, we investigate pressure temperature influence the formation annihilation of unrecoverable voids upon stripping. Stack are effective means initiate...
Abstract The plastic zone developed during elastoplastic contact may be effectively modeled as an inclusion in isotropic half space. This paper proposes a simple but efficient computational method to analyze the stresses caused by near surface inclusions of arbitrary shape. solution starts solving corresponding full space problem and proceeds annul acting normal tangential surface, where numerical computations are processed taking advantage fast Fourier transform techniques with parallel...
Abstract An elastic contact model for three-dimensional layered or coated materials under coupled normal and tangential loads, with consideration of partial slip effects, has been developed in this paper. The response functions calculating the displacements stresses were determined frequency domain by using Papkovich–Neuber potentials. problem was solved a numerical procedure based on conjugate Gradient method fast Fourier transform technique. pressure, surface shear tractions, stick ratios,...
Elastic-plastic contacts were analyzed by means of a three-dimensional numerical model based on minimization complementary energy, in which the effect plastic deformation is included superimposing residual displacement geometry contacting surface. The strain increments are determined through radial return method and J 2 flow theory, integrated with conjugate gradient (CGM) algorithm fast Fourier transform (FFT) technique for improving efficiency. results from present compared to those finite...
Polysaccharides are important biological macromolecules in all organisms, and have recently been studied as therapeutic agents for ulcerative colitis (UC). However, the effects of Pinus yunnanensis pollen polysaccharides on remains unknown. In this study, dextran sodium sulfate (DSS) was used to induce UC model investigate (PPM60) sulfated (SPPM60) UC. We evaluated improvement by analyzing levels intestinal cytokines, serum metabolites metabolic pathways, flora species diversity, beneficial...
In current military conflicts and civilian terrorism, blast-induced traumatic brain injury (bTBI) is the primary cause of neurotrauma. However, effects mechanisms bTBI are poorly understood. Although previous researchers have made significant contributions to establishing animal models for simulation bTBI, precision controllability in must be improved. Therefore, we established a novel rat model simulate blast-wave brain. To different extents injury, animals were divided into moderate severe...
Contacts involving partial slip are commonly found at the interfaces formed by mechanical components. However, most theoretical investigations of limited to homogeneous materials. This work proposes a novel and fast method for partial-slip contact material with an inhomogeneity based on equivalent inclusion method, where is replaced properly chosen eigenstrains. The stress displacement fields due eigenstrains formulated half-space solutions recently derived authors solved three-dimensional...
Line contact is common in many machine components, such as various gears, roller and needle bearings, cams followers. Traditionally, line modeled a two-dimensional (2D) problem when the surfaces are assumed to be smooth or treated stochastically. In reality, however, surface roughness usually three-dimensional (3D) nature, so that 3D model needed analyzing lubrication deterministically. Moreover, length often finite, realistic geometry may possibly include crowning axial direction round...
A mixed elastohydrodrynamic (EHL) model for journal bearings considering an axial flow due to shaft motion and misalignment is developed lubrication performance evaluation. new, faster EHL computing technology utilizing the odd–even successive overrelaxation (OESOR) parallel numerical iterative method proposed based on red–black (RBSOR) minimize execution time prolonged by complexity caused misalignments. The multithreaded scheme conducted OpenMP directive using different meshes threads...
