Computer aided analysis of viscous film flow along an inclined wavy wall
(1999)The steady, laminar flow of a Newtonian liquid along an inclined wavy wall is studied in a two-dimensional numerical experiment using the Galerkin finite element method. The dimensionless Navier-Stokes equations are solved ... -
Computer-aided estimation of acetone, methyl acetate, and chloroform diffusion coefficients in poly(vinyl acetate)
(2003)The diffusion coefficients of acetone, methyl acetate, and chloroform in amorphous poly(vinyl acetate) are estimated using the solvent evaporation method. The evaporation process from polymer solutions, cast in the form ... -
Coupled numerical simulation of low-cycle fatigue damage in metal components
(2021)A coupled cyclic plasticity-damage model is implemented for simulating low-cycle fatigue in metal components. Constitutive relations account for J2-flow theory with nonlinear kinematic/isotropic hardening, coupled with ... -
Finite element analysis of cyclically-loaded steel pipes during deep water reeling installation
(2016)Thick-walled steel pipes during their installation in deep water are subjected to combined loading of external pressure and bending, which may trigger structural instability due to excessive pipe ovalization. In the case ... -
Heating and cooling induced stresses and displacements in heat exchanger piles in sand
(2020)Heating and cooling of heat exchanger piles causes changes in the axial stresses in the pile and vertical pile displacements. Changes in axial stress (thermal stresses) are more significant in the case of fixed head piles, ... -
A homogenization model of the Voigt type for skeletal muscle
(2017)A three-dimensional constitutive model for skeletal muscle incorporating microstructural characteristics is developed and numerically implemented in a general purpose finite element program. The proposed model takes into ... -
Mechanical behavior of dented steel pipes subjected to bending and pressure loading
(2019)The presence of dents on steel pipeline wall may constitute a threat for pipeline structural safety. Experimental testing results supported by numerical simulations are reported, in an attempt to assess the structural ... -
Numerical simulation of JCO-E pipe manufacturing process and its effect on the external pressure capacity of the pipe
(2019)Large-diameter thick-walled steel pipes during their installation in deep-water are subjected to external pressure, which may trigger structural instability due to pipe ovalization, with detrimental effects. The resistance ... -
Permanent earthquake-induced actions in buried pipelines: Numerical modeling and experimental verification
(2018)Buried pipelines are often constructed in seismic and other geohazard areas, where severe ground deformations may induce severe strains in the pipeline. Calculation of those strains is essential for assessing pipeline ... -
Probabilistic damage identification of a designed 9-story building using modal data in the presence of modeling errors
(2017)Validity and accuracy of model based identification techniques such as linear finite element (FE) model updating are sensitive to modeling errors. Models used for the design and performance assessment of civil structures ... -
The Problem of Tension-Torsion of Pretwisted Elastic Beams Revisited
(2022)A one-dimensional technical theory for pretwisted isotropic linearly elastic beams loaded in tension and torsion was developed. The analysis was based on a kinematically admissible field written in terms of three generalized ... -
Structural behavior and design of high-strength steel welded tubular connections under extreme loading
(2020)The present work is motivated by the increasing need for cost-efficient solutions in offshore structural systems for wind energy production and for improvement of their structural performance. The structural behavior and ... -
Structural behavior of buried pipe bends and their effect on pipeline response in fault crossing areas
(2017)Pipe bends, often referred to as “elbows”, are special pipeline components, widely used in onshore buried steel pipelines. They are sensitive to imposed deformations and their structural behavior is quite flexible and ... -
The use of Knoop indentation for the assessment of the plastic properties of mortars and natural stones
(2017)The present work investigates the Knoop hardness of rocks and other pressure sensitive materials. We tested ten different types of rocks, a cement paste, and PMMA. We also analyzed existing experimental results for Mg-PSZ ...
