“…As another type of meshfree methods, DEM, has recently been successfully applied to model the fracture of solids such as ceramics [10], concrete [39] and even composite materials [40]. The particles in DEM are bonded together and the crack initiation and propagation is treated as the progressive breakings of bonds.…”

“…Also each of the material layers is of equal thickness h/4 and idealized as a homogeneous material. Constant displacement loading was applied on the 0˚ ply at both ends of the element with a constant horizontal velocity of 0.05 m/s , which represents for a quasi-static loading condition [28]. Figure 7 shows the comparisons for the through thickness distribution of the normal stress .…”

“…DEM has been used in our previous research of microbond test [28] and transverse cracking [29] of composite materials. The purpose of this research is not only to validate the application of DEM in terms of its advantages in the simulation of cracking density and stiffness reduction prediction, but also to highlight the potential of DEM in the future research application for composite damage mechanism, composite material design and optimization.…”

A representative element of the cross-ply laminate was modeled by the discrete element method (DEM) to analyze the stresses distribution. The DEM modeling results were compared with those from alternative approaches to validate the DEM model. The transverse cracking and interfacial delamination in [0˚1/90˚3] s and [90˚n/0˚1] s cross-ply laminates under transverse loading were analyzed by comparing crack densities as well as stiffness reduction with those from experiments and other numerical methods. It was found that the proposed DEM model can simultaneously capture the transverse cracking and delamination phenomenon, and can predict the variation of crack density and stiffness reduction accurately.

“…Kim et al [20,21] used DEM to simulate the damage of asphalt concrete which is a typical example of two-phase composite materials. Yang et al [22] used DEM to simulate the dynamic process of microbond test of single fiber reinforced composite with the consideration of matrix cracking as well as fiber/matrix interfacial debonding. Donze et al [23,24] simulated the impacts of rigid spherical nose shaped missiles on concrete beams with reinforcements.…”

A particle discrete element method (DEM) was employed to simulate transverse cracking in laminated fiber reinforced composites. The microstructure of the laminates was modeled by a DEM model using different mechanical constitutive laws and materials parameters for different constituents, i.e., fiber, matrix and fiber/matrix interface. Rectangular, hexagonal and random fiber distributions were simulated to study the effect of fiber distribution on the transverse cracking. The initiation and dynamic propagation of transverse cracking and interfacial debonding were all captured by the DEM simulation, which showed similar patterns to those observed from experiments. The effect of fiber volume fraction was also studied for laminae with randomly distributed fibers. It was found that the distribution and volume fraction of fibers affected not only the transverse cracking path, but also the behavior of matrix plastic deformation and fiber/matrix interface yielding in the material.
