Influence of muscle-tendon complex geometrical parameters on modeling passive stretch behavior with the Discrete Element Method [PDF]
, 2016 The muscle-tendon complex (MTC) is a multi-scale, anisotropic, non-homogeneous structure. It is composed of fascicles, gathered together in a conjunctive aponeurosis. Fibers are oriented into the MTC with a pennation angle. Many MTC models use the Finite

Discrete element method approach to modelling VPP dampers
MATEC Web of Conferences, 2018 In this paper, we present a novel approach to modeling and analysis of Vacuum Packed Particle dampers (VPP dampers) with the use of Discrete Element Method (DEM). VPP dampers are composed of loose granular medium encapsulated in a hermetic envelope, with

Slope Failure of Noncohesive Media Modelled with the Combined Finite–Discrete Element Method
Applied Sciences, 2019 Slope failure behaviour of noncohesive media with the consideration of gravity and ground excitations is examined using the two-dimensional combined finite⁻discrete element method (FDEM).

Advances in Civil Engineering, 2020 A brief literature review of numerical studies on excavation damage zone (EDZ) is conducted to compare the main numerical methods on EDZ studies. A hybrid finite-discrete element method is then proposed to model the EDZ induced by blasts.

Discrete element method, a tool to investigate complex thermo mechanical behaviour: application to friction stir welding [PDF]
, 2009 In material forming or cutting, the contact zone between the tool and the working piece is often very difficult to analyse because of diverse local phenomena. In the special case of FSW, a specific difficulty is the study of material mixing. In this work,

Track ballast modelling by discrete element method
Građevinar, 2019 An increase in axle load and travel speed causes faster degradation of track structure and, hence, of the ballast prism. Crushing of stone grains in ballast due to excessive contact forces among these grains causes degradation in the form of filling of ...

Boundary element method based on preliminary discretization [PDF]
Mathematical Models and Computer Simulations, 2014 The final publication is available at Springer via http://dx.doi.org/10.1134/S2070048214020082 A new numerical method for solving wave diffraction problems is given. The method is based on the concept of boundary elements; i.e., the unknown values are the field values on the surface of the scatterer. An analog of a boundary element method rather than a
