Confined granular flows on a heap: from simulations to experiments
EPJ Web of Conferences, 2017 Surface granular flows are studied by means of discrete element simulations. The investigation of their kinematic properties suggests the existence of two regimes: one close to the jamming, for which the shear rate increases with the angle of the flow ...

Numerical Simulation of Mechanical Properties of Soil Considering the Effect of Internal Erosion
Mathematics, 2023 The loss of fine particles from the skeleton formed by coarse particles due to seepage action significantly affects the grading, void ratio, and mechanical properties of soil. This results in several issues of engineering hazards. In order to analyze the

ON DEVELOPMENT OF THE INTERACTIVE DESIGN TOOL BASED ON ISOGEOMETRIC ANALYSIS
Acta Polytechnica CTU Proceedings, 2017 Isogeometric analysis is a new concept of Finite element method which has been proposed to bridge the gap between the CAD systems and the FEM solvers. In Isogeometric analysis, the same basis functions, typically splines or NURBS, are used for geometry ...

Facta Universitatis. Series: Mechanical Engineering, 2017 Composite laminates consisting of passive and multi-functional materials represent a powerful material system. Passive layers could be made of isotropic materials or fiber-reinforced composites, while piezoelectric ceramics are considered here as a multi-

Particle-scale insight into transitional behaviour of gap-graded materials – small-strain stiffness and frequency response [PDF]
E3S Web of Conferences, 2019 This study aims to develop a fundamental understanding of the role of fine particles on the small-strain stiffness of gap-graded granular soils. Stiffness was measured using cyclic triaxial probes, which give a measure of static stiffness, and dynamic ...

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

The Shear Strength of Granular Materials with Dispersed and Non-Dispersed Oversized Particles [PDF]
, 2013 Soils containing dispersed and non-dispersed large particles (greater than # 4 sieve) form part of many engineered fills, glacial tills, debris flows, and residual soil deposits.

Facta Universitatis. Series: Mechanical Engineering, 2019 Integration of classical, passive structures and active elements based on multi-functional materials resulted in a novel structural concept denoted as active structures. The new structural systems are characterized by self-sensing and actuation. Coupling
