Dented externally-pressurised pipes subjected to cyclic axial loading
(2019)The present paper describes a numerical investigation of the mechanical response of externally-pressurized dented stainless-steel pipes, subjected to reverse cyclic axial loading. This is the first part of a large-scale ... -
Effect of prior deformation and heat treatment on the corrosion-induced hydrogen trapping in aluminium alloy 2024
(2014)The nature of the corrosion-induced hydrogen trapping in Al-alloy 2024-T351 was studied by thermal desorption spectroscopy. The microstructure was altered by solution treatment and plastic deformation, prior to corrosion. ... -
Effect of retained austenite stability on cyclic deformation behavior of low-alloy transformation-induced plasticity steels
(2019)The retained austenite (RA) characteristics of Al-containing TRIP700 steels have been manipulated using varying bainitic isothermal transformation (BIT) processing. The microstructural evolution was investigated using ... -
Failure analysis of a welded steel pipe at Kullar fault crossing
(2017)The seismic response of a 2200-mm-diameter welded steel pipe at strike slip Kullar fault crossing in Izmit, Kocaeli during 1999 Kocaeli earthquake is investigated. The pipe was crossing the fault-line with an angle of 55° ... -
Fiber plasticity and loss of ellipticity in soft composites under non-monotonic loading
(2022)In this work, we relate fiber plasticity in soft composites to the loss of ellipticity of the governing equations of equilibrium of a composite under non-monotonic uniaxial loading. The loss of ellipticity strongly indicates ... -
Finite element analysis of industrial steel elbows under strong cyclic loading
(2011)Steel elbows are used in petrochemical facilities and power plants. In the case of an earthquake event, in addition to other service loads, they are subjected to strong repeated cyclic structural loading that may lead to ... -
Finite element modeling of trip steels
(2004)In this paper, a constitutive model that describes the mechanical behavior of steels exhibiting the "Transformation Induced Plasticity" (TRIP) phenomenon during martensitic transformation is presented. Multiphase TRIP ... -
Influence of plastic prestraining on the fatigue crack propagation rate of S355MC and S460MC structural steels
(2021)Cold forming induces significant plastic deformation at corner locations of structural steel members, resulting in both material strain hardening and the development of residual stresses, which influence the fatigue ... -
Low Cycle Fatigue Behavior of Plastically Pre-Strained HSLA S355MC and S460MC Steels
(2022)Cold roll forming used in the manufacturing of lightweight steel profiles for racking storage systems is associated with localized, non-uniform plastic deformations in the corner sections of the profiles, which act as ... -
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 ... -
STRUCTURAL RESPONSE OF SUBSEA PIPE ELBOWS UNDER MONOTONIC AND CYCLIC LOADING
(2022)Pipe bends (elbows) are commonly used components in subsea piping systems. They are quite flexible compared to the corresponding straight pipes and are used to reduce the reaction forces and moments at the supports and the ...
