Regardless of its origin, in the near future the challenge will not be how to generate data, but rather how to manage big and highly distributed data to make it more easily handled and more accessible by users on their personal devices. VELaSSCo (Vis

Realistic yet efficient representation of particle shape is a major challenge for the Discrete Element Method. This paper uses angle-of-repose and direct-shear test simulations to describe the influence of several shape representation methods, and th

The macroscopic response of a geomaterial is entirely determined by changes at the particle scale. It has been established that particle crushing is affected by particle size, shape and mineral composition and initial density; and the initiation of b

Efficient computation of cubature rules with application to new asymmetric rules on the triangle

Autor: Stefanos-Aldo Papanicolopulos

Publikováno v: Papanicolopulos, S 2016, ' Efficient computation of cubature rules with application to new asymmetric rules on the triangle ', Journal of computational and applied mathematics, vol. 304, pp. 73-83 . https://doi.org/10.1016/j.cam.2016.03.013

This paper presents a new, efficient method for computing cubature rules, based on least-squares minimisation and the use of orthogonal bases. The method, which can be applied for any integration domain, is tested here for the case of asymmetric cuba

Particle breakage can significantly change the fabric (size and shape of particles and contact network) of a granular material, affecting highly the material's macroscopic response. In this paper, oedometric compression tests are performed on zeolite
