Micromechanical analysis of composites by the generalized cells model

Concurrent Multi-Scale Modeling of Composites Under High Rates of Loading

“…1. The subdivision into a higher number of orthogonal cells as shown on the right hand side of Fig.1 was proposed in [2,9] and allows a more accurate representation of the fiber geometry. Additionally, this enables the user to assess a wide variety of fiber distributions and their respective interactions as each cell can be assigned different properties.…”

Three-dimensional evolution of mechanical percolation in nanocomposites with random microstructures

“…To predict the effective elastic properties of the composite, the three-dimensional micromechanics model, known as the Generalized Method of Cells (GMC) [30], was used. GMC is a periodic unit cell model that uses a rectangular repeating unit cell GMC's predictions of the effective elastic properties compare well to the classic Mori-Tanaka model (MT), [31,32] for two-phase composites [33], in the low volume fraction range where MT is assumed most valid.…”

Computational Implementation of a Thermodynamically Based Work Potential Model for Progressive Microdamage and Transverse Cracking in Fiber-reinforced Laminates

“…10,12,[24][25][26][27][28][29][30][31][32][33] In-plane damage mechanisms can also be captured with micromechanics models including repeating unit cell (RUC) and representative volume element (RVE) techniques, as well as other methods. 5,[34][35][36][37][38][39] Moreover, micromechanics models can be tied to the continuum scale using multiscale methods in which the RUC is homogenized to give the effective response of the continuum. [40][41][42][43][44][45] Commonly used techniques for introducing interlamina damage into a composite simulation include the virtual crack closure technique (VCCT), cohesive zone model (CZM) 10,[46][47][48] and discrete cohesive zone model (DCZM).…”
