Non-associated viscoplasticity coupled with an integral-type nonlocal damage model for mineral filled semi-crystalline polymers

Romain Balieu, Franck Lauro, Bruno Bennani, Tsukatada Matsumoto, Ernesto Mottola

A non-associated viscoplastic model coupled with nonlocal damage under finite strain framework is developed to simulate the non-isochoric deformation and the damage process exhibiting strain-softening of a 20% mineral filled semi-crystalline polymer. The logarithmic spin tensor properties linking...

Anisotropic damage induced by complex fibre orientations in short-fibre reinforced composites

Delphine Notta-Cuvier, Franck Lauro, Bruno Bennani

In this study, the behaviour of short-fibre reinforced composites is modelled in an original way that does not require complex homogenisation procedures. The composite is seen as the assembly of a matrix medium (metal or polymer) and several one-dimensional linear elastic fibre media. The matrix...

Damage of short-fibre reinforced materials with anisotropy induced by complex fibres orientations

Delphine Notta-Cuvier, Franck Lauro, Bruno Bennani, Romain Balieu

In this paper, a behaviour model for damageable elastoplastic materials reinforced with short fibres that have complex orientations is proposed. The composite material is seen as the assembly of the matrix medium and several linear elastic fibre media. Its macroscopic behaviour is computed thanks...

Experimental procedure to characterize the mode I dynamic fracture toughness of advanced epoxy resins

Vincent Joudon, G. Portemont, Franck Lauro, Bruno Bennani

Epoxy resins are widely used in Carbon Fiber Reinforced Polymers (CFRPs) for the aeronautical industry. They must ensure cohesion in most of the structural composite parts incorporated into the modern manufactured aircrafts. So fracture properties of epoxy resins are essential features to resist...

A fully coupled elastoviscoplastic damage model at finite strains for mineral filled semi-crystalline polymer

Romain Balieu, Franck Lauro, Bruno Bennani, Rémi Delille, Tsukatada Matsumoto, Ernesto Mottola

A phenomenological finite strain non-associated elastoviscoplastic model coupled with damage is proposed in order to simulate the behaviour of a 20% mineral filled semi-crystalline polymer for a large strain rate range under several loading conditions. In the proposed model, the direct relation...

An efficient modelling of inelastic composites with misaligned short fibres

Delphine Notta-Cuvier, Franck Lauro, Bruno Bennani, Romain Balieu

This paper deals with the modelling of the behaviour of short-fibre reinforced composites. The composite is seen as an assembly of a matrix medium and of several fibre media. Each fibre medium, characterised by its own orientation of fibres and volume fraction, is considered as a one-dimensional...

A new cohesive element for structural bonding modelling under dynamic loading

David Morin, Benjamin Bourel, Bruno Bennani, Franck Lauro, Denis Lesueur

The purpose of this paper is to propose a simplified macroscopic three-dimensional cohesive element dedicated to crash engineering. At the boundary between the CCZM (Continuous Cohesive Zone Method) and the DCZM (Discrete Cohesive Zone Method) approaches, this cohesive element includes an improved...
