Résumé : |
Fibre-reinforced polymers (FRP) have been progressively applied as structural materials during the past 50 years and are now extensively used in applications where, in spite of their high cost, their unique combination of low density, high stiffness and strength as well as toughness is a competitive advantage. Remarkable examples can be found in sectors such as aerospace, with modem commercial and military aircraft employing over 50% of composite materials by weight ; automotive, with electric cars pressing on low vehicle weight associated with extended battery ranges ; and also in the energy and sports sectors. |

- FIGURES : 1. Composite materials are used in a wide range of applications - 2. Local-to-global multiscale simulation strategy to conduct virtual mechanical tests of composite materials that explores the hierarchical structure of composite materials - 3. Failure envelope of a carbon-epoxy unidirectional ply predicted by the computational micromechanics module (VIPER) of the virtual test lab. The numerical results are correlated with the Puck failure-criteria - 4. Results of the computational mesomechanics module of the virtual test lab. a) Virtual open-hole compression (OHC) test coupons according to ASTM D6484/D64884 standard ; b) Virtual drop-weight impact tests according to ASTM D7136/D7136§ (two different impact energies) |
