A time-variant reliability approach for ageing marine structures with non linear behaviour

Résumé

Assessing efficiently the lifetime of ageing naval structures needs taking into account the random and temporal character of material properties, environmental conditions and loads. Time-variant reliability methods are a way to deal with this source of concern. A realistic prediction of the durability of industrial-type structures also requires considering non-linear material behaviours induced by plasticity, damage, etc. Therefore non-linear finite element calculations are needed to predict realistically the structure response. Combination of these two approaches is thus a promising way to improve safety and durability of structures especially for naval applications. To demonstrate its feasibility and difficulties, two reliability studies are proposed: the first one focusing on a corroded elasto-plastic plate submitted to a stochastic load and the second one dealing with adhesively-bonded assemblies taking into account the adhesive damage.
