Adaptive mesh generation in FEM from an optical interferometric phase map
نویسنده
چکیده
An approach hybrid optical-computational criterion to generate an adaptive refinement mesh to be used in mechanical structure analysis with Finite Element Method (FEM) is proposed. The numerical error to determine the refinement zones in adaptive meshing is substituted for an experimental weight function. Experimental optical phase map is used to define this weight function. This criterion permits adaptive two-dimensional mesh refinement in experimental critical zones as interruptions due to real edges or crack tips. The general criterion and algorithm are given. Two-dimensional refinement examples using experimental phase maps of displacement and fracture measuring using triangular elements in a rectangular domain are shown.

A mesh generation procedure to simulate bimaterials
It is difficult to develop an algorithm which is able to generate the appropriate mesh around the interfaces in bimaterials. In this study, a corresponding algorithm is proposed for this class of unified structures made from different materials with arbitrary shapes. The non-uniform mesh is generated adaptively based on advancing front technique available in Abaqus software. Implementing severa...
متن کاملAn OOP Approach for Mesh Generation of Multi-Region Models with NURBS
This paper presents an object-oriented approach for creating multi-region non-manifold models with NURBS. The main motivation is that the geometry and shape of realistic engineering objects are intrinsically complex, usually composed by several materials and regions. Therefore, automatic and/or adaptive meshing algorithms have become revealed themselves quite useful to increase the reliability ...

متن کاملSub-THz Carrier Frequency Generation Stabilized by Mach-Zehnder Interferometric Phase Detection Scheme
We propose a Mach-Zehnder interferometric phase detection for low phase noise subterahertz (THz) carrier frequency generation. In this scheme, phase fluctuation between two optical signals can be detected as the interference between their optical sidebands. Experimental result shows that, by controlling the interference to be constant, the phase noise is successfully reduced, which indicates ef...
