In spite the FEM is now routinely used in engineering practice in solid-state and fluid dynamics, its usage for MHD simulations has recently only begun and only few implementations exist so far. In this paper we present our MHD solver based on the Least-Square FEM (LSFEM) formulation. We ...

Although the discrete crack approach is occasionally preferred because it is based on a mature theory, the smeared crack analysis seems to be more often applicable to the typical FEM analyses encountered in engineering practice. The mechanisms of hydraulic fracturing in soil have been extensively studi...
Based on the example in practice, the slope stability before and after bolting was analyzed and the results are compared with thos from the traditional method. It shows that FEM can be used for solving the slope analysis problems. 展开 关键词:...
For large models, the computation time becomes prohibitively large and, inpractice, often explicit methods are used. In this contribution a strategy is presented that enablesthe application of implicit finite element simulations for large scale sheet forming analysis.Iterative linear equation solvers are...
In this engineering tool, 3D models in a COLLADA (COLLAborative Design Activity) [1] (.DAE format) can be uploaded from local memory or from a pre-designed geometry library. The 3D solids tool then volumetrically meshes the geometry using tetrahedral elements to a user defined level of ...
structures. It is a synergy of the standard approach to connection design (component method) and finite elements. This allows engineers to code-check steel connections of immense variety. CBFEM overcomes the limit of calculation possibilities in connection design while keeping engineers on the safe ...
In this section we describe the usage of the general purpose 2d- or 3d-truss element as described before in Sec. 4.6.4 for small strain regime by a real-sized engineering example. Obviously, the following model of a building site crane is very simplified, but it shows quite impressively th...
