Numerical simulations become a necessity when experimental approaches cannot cover the
required physical and time scale of interest. One of such area is a simulation of long-term …

Concrete is the most-used cementitious material and usually considered a three-phase
composite with a mortar matrix, aggregates, and interfacial transition zones, all of which can …

Since the mixed granular flows containing multiple non-spherical DEM models in complex
structures are still challenging for DEM applications, a unified method for creating level set …

In this research, we developed a new 2D triangular lattice model with axial and angular
springs to simulate fracture problems in composites. The inclusion of angular springs in the …

The high-pressure compaction of three dimensional granular packings is simulated using a
bonded particle model (BPM) to capture linear elastic deformation. In the model, grains are …

Spontaneous formation and evolution of discontinuities in solid media still poses one of the
significant challenges in solid mechanics and computational mechanics. To facilitate …

Dense architectured, granular, and other material systems based on the assembly of
discrete building blocks provide mechanical responses not ordinarily achieved in monolithic …

The layered rock masses with structural planes are widely distributed, among which the
transverse isotropy caused by the bedding structural plane has a great influence on the …

In this study, we explored the effects of different softening laws on the modelling of
progressive damage in unidirectional composites materials using a 2D lattice model. The …

A new non-uniform sequential mobile packing (NSMP) algorithm featuring an efficient
collision detection scheme was developed to rapidly generate representative volume …
