In this book, the authors present current research on non-linear analysis, from across the globe. Topics include modelling of the characteristics of inelastic members of reinforced concrete structures in seismic non-linear analysis; automatic estimation of the apnea-hypopnea index from oxygen saturation recordings using non-linear regression analysis; non-linearity in bridge structural analysis; non-linear analysis of spontaneous MEG activity in Alzheimer's disease; mesh free-enriched finite element methods for non-linear analysis of path-independent and path-dependent problems in solids; non-linear analysis research in biomedical engineering; and non-linear evolution analysis for flow during alloy crystallisation.
