LAYERWISE MODELS FOR THE STUDY OF HYBRID MULTILAYERED STRUCTURES.

Rawad Baroud (Ecole des Ponts ParisTech) Jean-François Caron (Navier Laboratory, Ecole des Ponts ParisTech) Robert Le Roy (Navier Laboratory, Ecole des Ponts ParisTech) Boumedienne Nedjar (Ecole des Ponts ParisTech)

 

A Layerwise Stress approach is used for the calculation of a civil engineering complex structure as combining wood innovation, crossed and openwork plywood, and a high performance concrete slab. Comparisons with other models and experiments are made.

MICRO-CT ANALISYS OF INTERLAMINAR GRADED INTERFACE STRENGTH (IGIS) COMPOSITES BASED ON A THERMOPLASTIC MATRIX

Luigi Sorrentino (National Research Council of Italy) Pietro Russo (Consiglio Nazionale delle Ricerche) Fabrizio Sarasini (Università di Roma La Sapienza) Jacopo Tirillò (Università di Roma La Sapienza) Fabienne Touchard (P' Institute) Laurence Chocinski-Arnault (Institute Pprime) David Mellier (Institute Pprime)

 

MicroCT analysis was used to investigate the actual damage mechanisms occurring in IGIS laminates and showed how the graded interface strength is capable of shifting fibre breakage at higher impact energies and a allow higher elastic recovery.

SIMULATION OF A METAL-THERMOPLASTIC COMPOSITE ASSEMBLY

Simon Paroissien (Institut de Recherche Technologique (IRT) Jules Verne) Patrick Rozycki (Institut de Recherche en Génie Civil et Mécanique) Thierry Renault (Faurecia)

 

This paper deals with an original way to simulate efficiently a complex multimaterial CMT Pin interface. Both a numerical and a multi scale analytical model are proposed and compared to an experimental campaign.

STAMP FORMING OF STEEL-BASED FIBRE METAL LAMINATE

Davood Rahiminejad (Australian National University) Adrian Lowe (Australian National University) Shankar Kalyanasundaram (Australian National University)

 

Stamp forming of a steel-based Fibre Metal Laminate was studied using a hemispherical punch at different blank holder forces and preheat temperatures. The strain evolution pattern was analysed with an in-situ 3D photogrammetric measuring system.

BUCKLING ANALYSIS OF ANISOTROPIC THIN-WALLED CIRCULAR CYLINDRICAL SHELLS SUBJECT TO COMBINED LOADING

Esmaeal Ghavanloo (Shiraz University) S. Ahmad Fazelzadeh (Shiraz University)

 

The governing equations are derived and analytical solution is presented for predicting the buckling behavior of the anisotropic thin-walled cylindrical shells subjected to combined loads by using the Flügge shell theory and complex method.

EXPERIMENTAL INVESTIGATION OF MOLDED-IN THREADS AS A NEW SOLUTION FOR LOAD TRANSFER IN THICK-WALLED GFRP APPLICATIONS

Marcel Bücker (Schäfer MWN GmbH) Jiri Duchoslav (Johannes Kepler University Linz) Nicole Motsch (Institute for Composite Materials)

 

When forming threads directly in thick walled GFRP instead of cutting them, the fatigue behavior can be increased significantly. 16 test series were done, with variation of thread, manufacuring method, laminate and load direction.

FAILURE ANALYSIS OF ULTRA-THIN CHOPPED CARBON FIBER TAPE REINFORCED THERMOPLASTIC IN MECHANICAL JOINTS

Linshu Meng (University of Tokyo) Hirokuni Wataki (University of Tokyo) Isamu Ohsawa (University of Tokyo) Jun Takahashi (University of Tokyo)

 

Pin-loaded test of Ultra-thin chopped carbon fiber tape reinforced thermoplastic (UT-CTT) material was conducted, special failure modes different from laminates composite were observed in failure process of UT-CTT, which shows very stable failure.
