Abstract Biodegradable porous Mg scaffolds are a promising approach to bone repair. In this work, 3D-spherical Mg–1.5Zn–0.2Ca (wt.%) were prepared by vacuum infiltration casting technology, and MgF 2 fluorapatite coatings designed control the degradation behavior of Mg-based scaffolds. The results showed that pores in composed main spherical (450–600 μm) interconnected (150–200 μm), porosity was up 74.97%. exhibited sufficient mechanical properties with compressive yield strength about 4.04...
The high-density polyethylene (HDPE) double-wall corrugated pipe, which is a kind of flexible widely used in municipal drainage networks. characteristics the surrounding soil and pipe bed, cover depth, backfill compaction, type pavement design, traffic loads are some major factors that affect stress deformation pipes. In this study, ABAQUS 3D finite element model was to analyze influence compactness, loads, diameter, hoop stiffness on mechanical characteristic an HDPE under loads. A series...
Concrete pipes are widely used in municipal drainage projects. Corrosion is a common issue affecting concrete pipes, causing leakage of environmental pollution, and road collapse. It necessary to study the mechanical properties corroded pipes. To investigate depth influence corrosion depths, widths, traffic loads, cover on characteristics buried under static series full-scale tests were carried out. Then, three-dimensional finite element model loads established based ABAQUS. Results showed...
Frequent accidents caused by underground pipeline damage are a widespread societal concern. Trenchless rehabilitation methods, particularly cured-in-place pipe (CIPP) lining, increasingly used for repair with great success. Existing research is mainly concerned practical improvements in and evaluating the performance of rehabilitation. In this study, model corroded buried concrete that had been rehabilitated CIPP was established using numerical Mesh-based parallel-Code Coupling Interface...
Current research was not dedicated to investigate the mechanical behavior of a concrete drainage pipe under multiphysical coupling conditions overburden pressure, traffic loads, groundwater, and fluids. This study proposes new numerical solution method for coupled stress, seepage, flow fields based on validated finite element model. The model developed by ABAQUS FLUENT then solved simultaneously using MpCCI (mesh‐based parallel‐code interface) platform. Results show that tensile stress at...
Abstract Fluctuations in the groundwater level make working conditions of concrete pipes below more complex than those above level. This paper describes application a three‐dimensional (3‐D) refined finite element (FE) model to analysis buried pipe subjected coupled effects traffic load and fluctuations. First, dynamic responses dry soil were investigated with full‐scale test an FE model. The results show that predicted similar observed field pipes. Then, based on numerical under saturated...
For flexible pipelines, the influence of backfill compaction on deformation pipe has always been focus researchers. Through finite element software, a three‐dimensional soil model matching exterior wall corrugation high‐density polyethylene was skillfully established, and “real” pipe‐soil interaction verified accuracy through field test. Based model, strain distribution at any position buried HDPE can be obtained. Changing location extent loose backfill, radial displacement distributions...
