描述

现代分析理论的疲劳加上知识的处理影响金属构成良好的基础设计机器零件是免费的从意想不到的失败。机器零件的疲劳设计:预期寿命提供信息和优化设计所需的工具。它强调实用的方法有效地解决疲劳问题,包括隐藏的风险最小化生产过程中可能出现的危险或暴露于环境。

提供的材料是有双重方法:理论方面的优秀报道是重音机器零件的实际插图的行为。理论方法结合了固体力学的基本原理,疲劳分析,裂纹扩展。的章节覆盖疲劳理论特别强调,从最基本的开始,发展到复杂的多轴非线性问题。

实用的方法集中于表面处理对疲劳寿命的影响,说明了许多在上雕琢平面的疲劳问题来自案例研究。失败的解决方案展示作者的详细分析,旨在作为预防指南。这本书的案例是一个独特的特性。使用的数值方法是有限元方法,并提出了明确的解释和说明。

机器零件的疲劳设计:预期寿命是一个非常有价值的工具练习设计工程师和工程的学生。
