Damage evolution of novel 3D textile-reinforced composites under fatigue loading conditions

For the simulation of the material degradation process during multiaxial fatigue loading of 3D textile-reinforced composites a new physically based damage model is developed based on the fracture mode concept (FMC) of CUNTZE and the continuum damage mechanics. For the damage analysis and the model parameter identification cyclic tests under superposed tension/compression-torque loading are performed. (C) 2009 Elsevier Ltd. All rights reserved.
