Circular tunnel in a gradient elastoplastic rock mass
(2020)This paper attempts to study the mechanical behavior of an elastoplastic rock mass around an underground circular excavation by using gradient theory. The problem (in plane conditions) is reduced to that of a circular hole ... -
Fatigue of textiles used in vascular surgery: Application to carotid endarterectomy
(2021)Fatigue is a material-based phenomenon playing a significant role in the mechanical behavior of components and structures. Although fatigue has been well studied for traditional materials, such as metals, its underlying ... -
Finite element analysis of buried steel pipelines under strike-slip fault displacements
(2011)The present paper investigates the mechanical behavior of buried steel pipelines, crossing active strike-slip tectonic faults. The fault plane is vertical and crosses the pipeline axis at a certain angle. The interacting ... -
Finite Element Analysis of the Mechanical Behavior of Mitered Steel Pipe Elbows under Bending and Pressure
(2016)Using finite element simulation tools, which account for both geometric and material nonlinearities, the bending capacity of mitered steel pipe bends is investigated. First, numerical results are reported on the elastic ... -
Finite element analysis of UOE manufacturing process and its effect on mechanical behavior of offshore pipes
(2016)Thick-walled steel pipes during their installation in deep-water are subjected to a combination of loading in terms of external pressure, bending and axial tension, which may trigger structural instability due to excessive ... -
Mechanical behavior of aluminum honeycomb sandwich structures under extreme low temperature conditions
(2019)The current study is an effort to characterize the mechanical response of panels that are used as structural elements at low temperature applications. For the above reason, plaques of aluminum honeycomb sandwich were exposed ... -
Mechanical behavior of buried steel pipelines crossing strike-slip seismic faults
(2011)The present paper investigates the mechanical behaviour of buried steel pipelines, crossing active strike-slip tectonic faults. The fault plane is vertical and perpendicular to the pipeline axis. The interacting soil-pipeline ... -
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 ... -
Mechanical Behavior of Steel Pipe Bends: An Overview
(2016)An overview of the mechanical behavior of steel pipe (elbows) is offered, based on previously reported analytical solutions, numerical results, and experimental data. The behavior of pipe bends is characterized by significant ... -
Mechanical behavior of steel pipes with local wall distortions under cyclic loading
(2012)Evaluating the severity of pipe wall distortions is a crucial step towards safeguarding the structural integrity of aging hydrocarbon pipeline infrastructure. The present research refers to the remaining life of oil and ... -
Numerical simulation of UOE pipe process and its effect on pipe mechanical behavior in deep-water applications
(2015)Large-diameter thick-walled steel pipes during their installation in deep-water are subjected to a combination of loading in terms of external pressure, bending and axial tension, which may trigger structural instability ... -
A second gradient elasto-plastic model for fatigue of small-scale metal components
(2010)Purpose - As the dimensions of structures are scaled down to the micro- and nano-domains, the mechanical behavior becomes size dependent and thus, the classical elasticity solutions cannot be expected to hold. In particular, ... -
Study on the dynamic behavior of arterial end-to-end anastomosis
(2014)Vascular disorders, such as atherosclerosis and aneurysms are treated by vascular surgery operations, and involve the stitching of disconnected human arteries with themselves or with artificial grafts. Stitching techniques ...
