On the macroscopic response and field statistics in particulate composites with elasto-plastic phases and random microstructures
(2021)In this article, we carry out a theoretical investigation of the macroscopic response and field statistics in two-phase particulate composites with elasto-plastic constituents and random microstructures under cyclic loading ... -
Prediction of crack growth following a single overload in aluminum alloy with sheet and plate microstructure
(2011)The fatigue crack growth behavior under constant amplitude and under single overload of 2024 aluminum alloy in sheet and plate product form has been investigated. Constant amplitude fatigue crack growth tests showed superior ... -
Probing the Evolution of Retained Austenite in TRIP Steel During Strain-Induced Transformation: A Multitechnique Investigation
(2018)X-ray diffraction analysis, magnetic force microscopy, and the saturation magnetization method have been employed to study the evolution of the percentage and size of retained austenite (RA) particles during strain-induced ... -
Retained austenite and mechanical properties in bainite transformed low alloy steels
(1995)Uniform ductility and formability of low alloy steels can be improved by the transformation plasticity effect of metastable retained austenite. In this work, intercritical annealing followed by bainite transformation ... -
SANICLAY: A new simple anisotropic clay plasticity model
(2007)SANICLAY is a new simple anisotropic clay plasticity model that builds on a modification of an earlier model with an associated flow rule, in order to include simulations of softening response under undrained compression ... -
Simulation of industrial elbow response under strong cyclic loading
(2011)Elbow components are widely used in industrial facilities as parts of piping/tubing systems. Their performance under severe loading conditions may be critical for the structural integrity of an industrial facility In the ... -
Simulation of piping ratcheting experiments using advanced plane-stress cyclic elastoplasticity models
(2019)Industrial steel piping components are often subjected to severe cyclic loading conditions which introduce large inelastic strains and can lead to low-cycle fatigue. Modeling of their structural response requires the ... -
Stability of confined thin-walled steel cylinders under external pressure
(2009)The present paper investigates the structural stability of thin-walled steel cylinders surrounded by an elastic medium, subjected to uniform external pressure. A two-dimensional model is developed, assuming no variation ... -
Steel elbow response under strong cyclic loading
(2012)The present study examines the behavior of steel pipeline elbows subjected to strong cyclic loading conditions. A set of experiments is conducted where in-plane cyclic bending with constant amplitude is applied on the elbow ... -
A strain-gradient isotropic elastoplastic damage model with J3 dependence
(2019)A “plastic-strain-gradient” version of an isotropic elastoplastic damage model that depends on the third invariant J3 of the stress deviator is developed. The model is based on the “non-local” equivalent plastic strain ep ... -
A strategy for synthetic microstructure generation and crystal plasticity parameter calibration of fine-grain-structured dual-phase steel
(2020)This study aims to establish a strategy for bridging the microstructure and mechanical properties of fine-grain-structured dual-phase steel. A complete workflow is built up commencing with the microstructure observations ... -
TRIP steels: A multiscale computational simulation and experimental study of heat treatment and mechanical behavior
(2020)A multiscale investigation of the microstructure and the mechanical behavior of TRIP steels is presented. A multi-phase field model is employed to predict the microstructure of a low-alloy TRIP700 steel during a two-stage ... -
Underground circular openings in elastoplastic rocks: Strain gradient and size effects
(2020)A special form of gradient elasticity and a deformation version of gradient plasticity are employed to derive analytical solutions for the problem of an unsupported underground circular opening in an elastoplastic rock ...
