本书以有限单元基本理论为重点，以MATLAB程序为平台，以工程实例为背景，介绍 了有限元法及其程序设计方法。 本书讲述结构分析中有限元法的基本原理，单元类型包括平面杆系，空间杆系，平面等 参元，空间等参元，薄板壳单元和厚板壳单元等。内容涉及杆系结构、平面问题、空间问题和板壳问题。以结构线弹性静力分析为主，同时也讲述了结构的振动、稳定和动力响应分析。(This book is the basic theory of finite elements as the key to the MATLAB program as a platform to project examples as the background, the finite element method and its programming. This book describes the structural analysis of the basic principles of the finite element method, cell types including flat bar, space bar, flat isoparametric element, space isoparametric element, sheet shell and thick shell element and so on. Covering the truss structure, flat issues, space issues and shell problems. Structural linear elastic static analysis-based, but also about the structural vibration, stability and dynamic response analysis.)

遗传算法是计算机科学人工智能领域中用于解决最优化的一种搜索启发式算法，是进化算法的一种。这种启发式通常用来生成有用的解决方案来优化和搜索问题。进化算法最初是借鉴了进化生物学中的一些现象而发展起来的，这些现象包括遗传、突变、自然选择以及杂交等。(In the field of artificial intelligence, a genetic algorithm (GA) is a search heuristic that mimics the process of natural selection. This heuristic (also sometimes called a metaheuristic) is routinely used to generate useful solutions to optimization and search problems.[1] Genetic algorithms belong to the larger class of evolutionary algorithms (EA), which generate solutions to optimization problems using techniques inspired by natural evolution, such as inheritance, mutation, selection, and crossover.)
