Multiscale Modeling of the effect of sub-ply voids on the failure of composites: A progressive failure model

The effective fracture behavior of a fiber-reinforced composite depends on both the design and manufacturing of the material. During manufacturing several type of defects can occur. One of these defects are micro-voids on the sub-ply level. These can consist of either matrix voids or gaps between the fibers due to the inability of the resin to...

Multiscale Finite Volume Method for Coupled Single-Phase Flow and Heat Equations in Fractured Porous Media: Application to Geothermal Systems

Modern geoscience challenges motivate the development of advanced simulation methods for large-scale geothermal fields, where single- or multi-phase flow is coupled with heat transfer equation in heterogeneous fractured formations. The state-of-the-art multiscale formulation for fractured media (F-AMS; Tene et al., JCP, 2016) develops an...

Generalized grain cluster method for multiscale response of multiphase materials

A multiscale approach termed the generalized grain cluster method (GGCM) is presented, which can be applied for the prediction of the macroscopic behavior of an aggregate of single crystal grains composing a multiphase material. The GGCM is based on the minimization of a functional that depends on the microscopic deformation gradients in the...
