Buckling design of confined steel cylinders under external pressure
(2010)Thin-walled steel cylinders surrounded by an elastic medium, when subjected to uniform external pressure may buckle. In the present paper, using a two dimensional model with nonlinear finite elements, which accounts for ... -
A framework for formulating and implementing non-associative plasticity models for shell buckling computations
(2022)In modelling the behavior of thick-walled metal shells under compressive loads, the use of J2 flow theory can lead to unrealistic buckling estimates, while alternative ‘corner’ models, despite offering good predictions, ... -
A new concept for improving the structural resilience of lap-welded steel pipeline joints
(2022)Lap-welded steel joints are widely used in steel pipelines for water transmission, and their structural resistance is essential for safeguarding pipeline integrity and functionality after severe earthquakes or other ... -
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: ...
