摘要
The paper demonstrates that the mesh superposition (MSP) based finite element (FE) models of a textile composite unit cell can be used for adequate prediction of damage- and matrix plasticity-induced nonlinearity of the composite stress-strain response under tensile and shear loading. An elasto-plastic thermodynamically consistent damage model is implemented for matrix damage simulations. The intra-yarn damage initiation and propagation are simulated using Puck's damage criterion and a continuous damage mechanics model. The numerical simulations are validated by a comparison with experimental results for tension and shear loading of a plain weave glass/epoxy laminate. © 2022 Elsevier Ltd
