Computational Modelling Strategies for Nonlinear Response Prediction of Corroded Circular RC Bridge Piers

Advances in Materials Science and Engineering, 2016
A numerical model is presented that enables simulation of the nonlinear flexural response of corroded reinforced concrete (RC) components. The model employs a force-based nonlinear fibre beam-column element. A new phenomenological uniaxial material model

Nonlinear hydroelastic FSI model for stability analysis of foam sandwich beams under viscous water flow

Journal of Ocean Engineering and Science
Within the framework of an equivalent single-layer beam theory incorporating moderately large deformations at contact surface, a nonlinear hydroelastic fluid-structure interaction (FSI) model is developed to investigate the buckling and postbuckling ...
