Abstract :
[en] This paper presents the construction of a mean-field homogenization (MFH) surrogate for nonlinear stochastic multiscale analyses of two-phase composites that allows the material response to be studied up to its failure. The homogenized stochastic behavior of the studied unidirectional composite material is first characterized through full-field simulations on stochastic volume elements (SVEs) of the material microstructure, permitting to capture the effect of the microstructural geometric uncertainties on the material response. Then, in order to conduct the stochastic nonlinear multiscale simulations, the microscale problem is substituted by a pressure-dependent MFH reduced order micromechanical model, that is, a MF-ROM, whose properties are identified by an inverse process from the full-field SVE realizations. Homogenized stress-strain curves can be used for the identification process of the nonlinear range, however, a loss of size objectivity is encountered once the strain softening onset is reached. This work addresses this problematic introducing a calibration of the energy release rate obtained with a nonlocal MFH micromechanical model, allowing to scale the variability found on each SVE failure characteristics to the macroscale. The obtained random effective properties are then used as input of a data-driven stochastic model to generate the complete random fields used to feed the stochastic MF-ROM. To show the consistency of the methodology, two MF-ROM constructed from SVEs of two different sizes are successively considered. The performance of the MF-ROM is then verified against an experimental transverse-compression test and against full-field simulations through nonlocal Stochastic Finite Element Method (SFEM) simulations. The implementation of the energy release rate calibration allows to conduct stochastic studies on the failure characteristics of material samples without the need for costly experimental campaigns, paving the way for more complete and affordable virtual testing.
