In this thesis a constitutive model is developed for the numerical prediction of UD composite
material behaviour under impact loading. Impact induced loading usually results in three …

An improved experimental method for characterizing dynamic delamination growth in
composite structures has been developed and verified using high speed photography and …

This study presents a computational model for deformation behaviour of near-equiatomic
NiTi holey plates using finite element method. Near-equiatomic NiTi alloy deforms via stress …

Aircraft structures should endure tyre debris impacts. Therefore, numerical simulations which
are able to predict such phenomena are highly appreciated for the aircraft structures design …

Multilayer structures are frequently used for military impact protection applications. For low-
velocity impacts, they can be made from a wide variety of materials, including metallic and …

The finite length of strain gauges may induce filtering effects when measuring impact events.
In this study, we are interested in quantifying these effects. Precisely, we determined the cut …

When a penetrator penetrates a target, security issues such as detonation and deflagration
sometimes occur in the embedded explosive under an extreme environment with high …

Under plane stress conditions, most micromechanical and phenomenological models
predict a minimum in ductility for plane strain tension stress state. Therefore, the stress state …

Liquid Natural Gaz-LNG-carriers must provide cryogenic reliability and safety for at least 40
years. Most of the insulation systems belong to the so-called membrane type, in which the …

Cette thèse s' est déroulée dans le cadre du projet TOLEDO (Tolérance aux dommages par
impact des réservoirs hyperbares) piloté par Air Liquide en partenariat avec le CEA Le …
