Nonlinear energy functionals appearing in the calculus of variations can be discretized by finite element (FE) method and formulated as a sum contributions from local elements. A fast evaluation containing first order gradient terms is central part this contribution. We describe vectorized implementation using simplest linear nodal (P1) elements which all are evaluated at once without loop over...
Abstract Sustainability in construction of tunnel is very important to reduce environmental impact and also minimal use earth resources. Therefore, numerical modelling proposing at design stage achieved this objective. To evaluate the changes soil settlements during excavation, empirical, analytical, methods have been frequently applied movement research method effective anticipating possible u...
Various structural discontinuities, which form a discrete fracture network, play a significant role in the failure conditions and stability of the rock masses around underground excavations. Several continuum numerical methods have been used to study the stability of underground excavations in jointed rock masses but only few of them can take into account the influence of the pre-existing natur...
A new finite element method/boundary method (FEM/BEM) scheme is proposed for the solution of 2D magnetic static and quasi-static problems with unbounded domains. The novelty an original approach in treatment outer region. related domain integral eliminated at discrete level by using approximation fundamental solutions (Green’s functions) every node mesh. This “FEM-Green” replaces standard bound...
− There are a number of algorithms for interactively modeling deformable objects, such as soft human tissues. Because of the desire for real-time performance, approximations are made to quickly calculate deformations. This paper proposes accuracy metrics and benchmarks to allow a systematic comparison of simulation algorithms for deformable objects in 2D and 3D. We implement and compare the com...
Fluorescence signals of quantum dots (QDs) influenced by different array structures of gold-coated silicon nanorods (SiNRs) were investigated via experimental observations and two-dimensional (2D) finite element method (FEM) simulations. On the densest gold-coated SiNRs array structure, the highest QD fluorescence quenching rates were observed and on the sparsest array structure, the highest QD...
