本书提出板壳有限元Coons曲面构造法。它摒弃了传统的一致插入法,为直接构造各种用途各类板壳矩形元计算模型提供了简捷有效、灵活多样、几何意义直观、力学概念清晰的研究方法。它是板壳有限元与计算几何Coons曲面相结合的产物,是两门学科的交叉学科,是计算力学与计算几何造型设计的统一。它推广了计算几何的应用范围又增添了它的内涵,同时为板壳有限元的研究开拓了新的途径。它的发展将同计算几何、计算机绘图和CAD设计携手并肩向前发展,具有很大的潜力和发展前景。本书内容包括:第一章介绍板壳有限元Coons曲面法,构造出各类板壳矩形元;第二章介绍几个实
This book proposes a plate shell finite element Coons surface construction method. It abandons the traditional consistent insertion method and provides a simple, effective, flexible, intuitive geometrical concept and clear mechanical concept for directly constructing various types of plate and shell rectangular element calculation models for various purposes. It is a product of the combination of plate shell finite element and computational geometry Coons surface. It is an interdisciplinary subject of two disciplines and is a unity of computational mechanics and computational geometry modeling design. It promotes the application scope of computational geometry and adds its connotation. At the same time, it opens up new ways for the study of plate shell finite element. Its development will go hand in hand with computational geometry, computer graphics and CAD design. It has great potential and development prospects. The content of this book includes: The first chapter introduces the plate element finite element Coons surface method, constructs each kind of plate shell rectangular element; The second chapter introduces several real
