“…Both the elastic behaviour and the damage progression have to be covered by the model. In the present study, a continuum damage mechanics model was adopted, which is based on the Ladeveze model for unidirectional plies [42][43][44][45] and extended for textile fabrics by Johnson and Simon [46], implemented as a VUMAT user subroutine in Abaqus/Explicit. The constitutive stress-strain relations are formulated in a local Cartesian coordinate system with base vectors aligned with the warp and weft directions.…”

Abstract A low velocity impact study of aircraft tire rubber on 3D textile-reinforced composite plates was performed experimentally and numerically. In contrast to regular unidirectional composite laminates, no delaminations occur in such a 3D textile composite. Yarn decohesions, matrix cracks and yarn ruptures have been identified as the major damage mechanisms under impact load. An increase in the number of 3D warp yarns is proposed to improve the impact damage resistance. The characteristic of a rubber impact is the high amount of elastic energy stored in the impactor during impact, which was more than 90% of the initial kinetic energy. This large geometrical deformation of the rubber during impact leads to a less localised loading of the target structure and poses great challenges for the numerical modelling. A hyperelastic Mooney-Rivlin constitutive law was used in Abaqus/Explicit based on a step-by-step validation with static rubber compression tests and low velocity impact tests on aluminium plates. Simulation models of the textile weave were developed on the meso-and macro-scale. The final correlation between impact simulation results on 3D textile-reinforced composite plates and impact test data was promising, highlighting the potential of such numerical simulation tools.

“…The shear response of the textile composite is mainly dominated by the nonlinear behaviour of the matrix material, which includes both plasticity and stiffness degradation due to matrix micro-cracking expressed by damage variable d 12 . Further details of the model and mechanical formulae can be found in [46].…”

Abstract-A finite element tool was used to simulate the structural and damage response of honeycomb sandwich composites subjected to low-velocity impact, under different energy. Damage evolution such as composite skins failure, and collapse of honeycomb core was assessment by different damage models. And interlaminar damage was assessed by cohesive laws. The nonlinear behavior of honeycomb was simulated by a crushable foam plasticity model. Results of finite element simulation were compared with falling weight impact test on honeycomb sandwich panels consisting of carbon fiber preparation facesheets bonded to paper honeycomb structure foam. Good agreement and Acceptable error was obtained between predictions and experiments in terms of force histories, force-displacement curves and dissipated energy. The proposed model was also capable of simulating correctly nature and size of impact damage, capturing the features of delimitaztions between core and different layers.
