Abstract

. In this paper, the new Geomiso SEA software (www.geomiso.com) is proposed for inelastic static isogeometric analysis with shell elements and splines. Geomiso SEA offers an innovative way to merge geometric design with mesh generation, by creating, with its modern user interface, 3D models as tensor product grids. The utilization of the exact mesh for analysis eliminates geometric errors, while there is no need of repeating the geometry design for refinement purposes. In contrast, the standard finite element technique, not only cannot fully utilize the available data of the exact mesh, but also makes engineers unable to benefit from advanced spline techniques. Real world and industry applications on both thick (Mindlin-Reissner) and thin (Kirchhoff – Love) shells are demonstrated with a comparison between Geomiso

用Geomiso SEA建模和分析现实世界和工业应用:一种新的混合CAD/CAE软件，用于非弹性静力等几何壳体分析和先进样条技术的三维设计

．本文提出了新的Geomiso SEA软件(www.geomiso.com)，用于壳单元和样条的非弹性静力等几何分析。Geomiso SEA提供了一种将几何设计与网格生成相结合的创新方式，通过其现代用户界面创建张量产品网格的3D模型。利用精确网格进行分析消除了几何误差，同时不需要重复几何设计以进行细化。相比之下，标准有限元技术不仅不能充分利用精确网格的可用数据，而且使工程师无法受益于先进的样条技术。通过对Geomiso的比较，演示了厚壳(Mindlin-Reissner)和薄壳(Kirchhoff - Love)在实际世界和工业中的应用
