Buried steel pipelines crossing strike-slip faults
(2012)The paper examines the behaviour of buried steel pipelines crossing active strike-slip faults. The vertical fault plane is crossed by the pipeline at an angle ranging between zero and 45 degrees, causing significant plastic ... -
Conical indentation of incompressible rubber-like materials
(2009)In the last decade, the indentation test has become a useful tool for probing mechanical properties of small material volumes. In this context, little has been done for rubber-like materials (elastomers), although there ... -
Earthquake resistant design and rehabilitation of masonry historical structures
(2005)A general methodology for the earthquake resistant design and rehabilitation of damaged masonry historical structures is presented. The whole process is illustrated through a case study: The rehabilitation of Zoodohos Pigi ... -
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 Discrete Circular Dislocations
(2010)The present work gives a systematic and rigorous implementation of (edge type) circular Volterra dislocation loops in ordinary axisymmetric finite elements using the thermal analogue and the integral representation of ... -
Finite element analysis of UOE pipes under external pressure and bending
(2014)Thick-walled steel pipes manufactured through the UOE process are used in deep-water pipeline applications for the safe and cost-effective transmission of hydrocarbon energy resources. Such pipes are subjected to bending ... -
Mechanical behavior and wrinkling of lined pipes
(2012)The paper focuses on wrinkling of lined pipes (sometimes referred to as clad pipes) under bending loading, where a corrosion-resistant thin-walled liner is fitted inside a carbon-steel outer pipe. The problem is solved ... -
Model-reduction techniques for Bayesian finite element model updating using dynamic response data
(2014)This work presents a strategy for integrating a class of model reduction techniques into a finite element model updating formulation. In particular a Bayesian model updating approach based on a stochastic simulation method ... -
Nonlinear gear transmission system numerical dynamic analysis and experimental validation
(2014)The main objective of the present work was to accurately predict the dynamic response of a gear transmission system. First, a nonlinear mathematical model is introduced. In this model, the housing of the gearbox is modeled ... -
Numerical implementation of J 2 non-associative flow plasticity models
(2009)The present paper describes a J2 non-associative plasticity model, which takes into account the "corner-like" effects at the loading point on the yield surface, and is suitable for shell buckling calculations. The plastic ... -
On the seismic behaviour and design of liquid storage tanks
(2011)The paper examines some special issues on the structural behaviour of upright-cylindrical liquid storage tanks, which are widely used in industrial facilities and for water storage. Two main design standards are considered: ... -
Pipe-soil interaction and pipeline performance under strike-slip fault movements
(2015)The performance of pipelines subjected to permanent strike-slip fault movement is investigated by combining detailed numerical simulations and closed-form solutions. First a closed-form solution for the force-displacement ... -
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 ... -
Stability of long transversely-isotropic elastic cylindrical shells under bending
(2010)The present paper investigates buckling of cylindrical shells of transversely-isotropic elastic material subjected to bending, considering the nonlinear prebuckling ovalized configuration. A large-strain hypoelastic model ... -
Wedge indentation of elastic-plastic layered substrates: Designing against contact-induced plasticity
(2009)The present paper investigates the indentation of plastically graded substrates by wedge indenters. Substrates made of graded materials are often encountered in nature or are artificially produced. The variation of the ... -
Wrinkling of lined pipes under bending
(2012)The present study is motivated by the use of lined pipes in energy pipeline applications (oil, gas, etc.) where a corrosion-resistant thin-walled liner is fitted inside a carbon-steel outer pipe. The paper focuses on ...
