Advanced finite element techniques in simulation of the materials behavior under mechanical loading are reviewed. Advantages, limitations and perspectives of different approaches to the simulation of deformation, damage and fracture of materials taking into account their microand mesostructure are analyzed. Development of the methods of simulation of different aspects of the materials behavior ...

We develop a finite-element method for the simulation of dynamic fracture and fragmentation of thin-shells. The shell is spatially discretized with subdivision shell elements and the fracture along the element edges is modeled with a cohesive law. In order to follow the propagation and branching of cracks, subdivision shell elements are pre-fractured ab initio and the crack opening is constrain...

The mixing behaviors of dry and wet granular materials in gas fluidized bed systems were investigated computationally using the combined Computational Fluid Dynamics and Discrete Element Method (CFD-DEM). Dry particles were observed to mix fairly rapidly during the fluidization process due to vigorous relative motions between particles induced by the flow of gas. In contrast, due to the presenc...

The application of discrete element modelling (DEM) to cohesive fine powders in industrial processes, such as additive manufacturing, requires accurate and efficient calculations van der Waals interaction forces. In DEM community, it is a general practice reduce particle stiffness accelerate the simulations; however, this study shows that, for particles, there are many cases where previously pr...
