THE INFLUENCE OF LOCAL DEFECTS AND NONLINEAR MATRIX BEHAVIOUR ON THE FAILURE PROCESS OF FIBER REINFORCED COMPOSITES
Christian Marotzke (BAM Federal Institute for Materials Research and Testing) Titus Feldmann (BAM Federal Institute for Materials Research and Testing)
The stress and strain field arising in a unidirectional composite ply is analysed by means of a finite element model, focussing on the difference between elastic and plastic matrix material behaviour.
ON THE ROLE OF SHEAR TRANSFER MECHANISMS IN THE LONGITUDINAL TENSILE FAILURE OF CFRP COMPOSITES
Gianmaria Bullegas (Imperial College London) Silvestre Pinho (Imperial College London) Soraia Pimenta (Imperial College London)
A three-Dimensional (3D) Fibre Bundle Model (FBM) has been developed to simulate the longitudinal tensile failure and predict the statistical strength distribution of CFRP bundles of different sizes.
FINITE ELEMENT IMPLEMENTATION OF A MODEL FOR LONGITUDINAL COMPRESSIVE DAMAGE GROWTH WITH FRICTION
Sérgio Costa (Swerea SICOMP) Renaud Gutkin (Swerea SICOMP) Robin Olsson (Swerea SICOMP)
A model for the longitudinal response of laminated fibre-reinforced composites during compressive damage growth is implemented in a Finite Element (FE) package and validated for mesh objectivity. The current work details the FE implementation.
A MODEL FOR THE PREDICTION OF TRANSVERSE CRACK AND DELAMINATION DENSITY PREDICTION BASED ON A STRENGTH AND FRACTURE MECHANICS PROBABILISTIC APPROACH
Hortense Laeuffer (CNES) Brice Guiot (University of Bordeaux) Jean-Christophe Wahl (I2M - Arts et Métiers ParisTech) Nicolas Perry (Arts et Metiers ParisTech) Florian Lavelle (CNES) Christophe Bois (I2M - Arts et Métiers ParisTech)
A damage meso-model with strength and energy criteria was introduced. Damage growth is managed by Fracture Mechanics using the energy release rates. Numerical and experimental results are presented.
AN EXPERIMENTAL METHOD TO DETERMINE THE LONGITUDINAL INTRALAMINAR FRACTURE TOUGHNESS OF HIGH TENSILE STRENGTH FIBRE-REINFORCED UNIDIRECTIONAL COMPOSITES
Haibao Liu (Queen's University Belfast) Brian Falzon (Queen's University Belfast) Wei Tan (Queen's University Belfast)
This paper proposes a simple, yet novel, improvement on the testing of a CT composite specimen for the measurement of high-strength fibre-dominated intralminar fracture toughness.
NUMERICAL AND EXPERIMENTAL STUDY ON THE FAILURE OF NON-CONVENTIONAL LAMINATES
María Luisa Velasco López (University of Seville) Federico París (University of Seville) Juan Carlos Marín (University of Seville) Alberto Barroso (University of Seville)
ANALYSIS OF THE MATRIX TRANSVERSE DAMAGE IN A UD PLY OF AN UNBALANCED HYBRID PEEK-CARBON/GLASS COMPOSITE UNDER COMBINED STATIC LOAD
Nassira Boulebbad-Gomez (Airbus Helicopters) Jean-Paul Charles (Airbus Helicopters) Noël Lahellec (LMA-CNRS) Christian Hochard (LMA-CNRS)
A new material for a better identification of the model parameters for matrix transverse damage. Off-axis quasi-static tensile tests with loading/unloading cycles done using flat dumbbell-shaped specimens. Damage evolution of specimen is non linear.
ANALYSIS OF TRANSVERSE COMPRESSION AND IN-PLANE SHEAR IN UNIDIRECTIONAL COMPOSITES BY A PROGRESSIVE DAMAGE MODEL IN PRESENCE OF FIBER ROTATION
Sina Eskandari (University of Porto) Francisco Andrade Pires (University of Porto) Pedro Camanho (University of Porto) Antonio T. Marques (University of Porto)
An extended model is proposed to incorporate finite fiber rotation in fiber reinforced plastic laminates during the continuous damage evolution using continuum mechanics. The model prediction will be assessed with a set of experimental data.
CHARACTERIZATION AND MULTI-SCALE MODELING OF THE TRANSVERSE COMPRESSION OF THICK RTM-PROCESSED UNI-DIRECTIONAL SAMPLES
Jeremy Chevalier (Université Catholique de Louvain) Y.A. Janssens (Universit´e catholique de Louvain) Pedro Camanho (University of Porto) Thomas Pardoen (Université Catholique de Louvain) Frederic Lani (Ucl)
Thick RTM-processed unidirectional samples were produced and tested in transverse compression. The experimental results were confronted to micro-mechanical analyses on RVE with well identified constituents’ properties as input arguments.
DAMAGE REPRESENTATION AND DAMAGE EVOLUTION FOR LINEAR VISCOELASTIC UD COMPOSITE MATERIAL
Fei Xu (University of Nottingham) Arthur Jones (University of Nottingham) Shuguang Li (University of Nottingham)
Damage representation and damage evolution law for linear viscoelastic UD composites are built in this paper. A simple example is made to explain how to use this damage model.
