“…Quite a number of authors have demonstrated the accuracy of RVE models to predict stiffness, strength and fracture mechanisms of unidirectional (UD) FRPs under different loading conditions [4][5][6][7][8]. Moreover, RVE models have served to determine the complete failure surfaces of such materials [9][10][11][12][13]. By contrast, the volume of work that deals with the prediction of mechanical properties of woven composites based on a multiscale modelling approach is relatively small [14,15].…”

The mechanical properties of woven composites can be predicted by using a multiscale modelling approach. The starting point to its application is the microscale (the level of fibres, matrix and interfaces), that allows the computation of the homogenised behaviour of the yarn. The aim of this work was to predict the yarn-level behaviour of a thermoplastic-based woven composite in order to allow the formulation of a representative constitutive model that can be used to predict ply properties at the mesoscale. To accomplish this purpose, an insitu characterisation of the microconstituents was carried out. This served to generate inputs for three different representative volume element (RVE) models that allowed predicting the yarn longitudinal, transverse and shear responses. These mechanical characteristics allowed the determination of homogenised yarn constitutive behaviour which was found to be characterised by significant nonlinearity until failure, specially in transverse and shear directions.

“…In addition, it could be used to predict initiation and propagation of the fibermatrix interfacial decohesion and propagation at every point in the laminate, were found to be in good agreement with experimental results. Romanowicz [29] employed the numerical homogenization methods to predict the strength of unidirectional FRP lamina under a combination of the transverse compression and axial tension. The failure modes were found to be mainly due to fiber breakage, fiber/matrix debonding, and matrix plastic deformation.…”

h i g h l i g h t s A continuum damage model was implemented via user material subroutine to model fiber failure. The Mohr-Coulomb plastic criterion were used to model the epoxy behavior. The cohesive surfaces were used to simulate the fiber-matrix interface damage. Different analytical micromechanics theories were verified by the test results. Numerical homogenization methods effectively predicted the pultruded lamina macroscopic properties.

In this paper, compressive material tests on unconfined/confined resin and steel reinforced resin were experimentally evaluated in order to validate the numerical results. The uniaxial model which combines damage mechanics and Ramberg-Osgood relationship is proposed in this paper to describe the uniaxial compressive behaviour of resin and steel reinforced resin. Numerical homogenization is conducted to predict the tensile and shear behaviour of steel reinforced resin after validated by compressive material test results. The friction angle , the ratio of the yield stress in triaxial tension to the yield stress in triaxial compression K, and the dilation angle of the linear drucker-prager plastic model are obtained based on experiments and numerical homogenization simulation. The confinement effects on resin and steel reinforced resin could be effectively simulated by combing above parameters and uniaxial compressive model. Finite element simulations on unconfined/ confined resin and steel reinforced resin material tests were conducted to validate the material parameters proposed in this paper. A good agreement is observed, indicating the model and parameters proposed in this paper could be effectively used in the finite element simulation of injected bolts.
