一工程力学的分析与研究方法和其它自然学科一样,可以归纳为科学实验、理论分析和数值计算三个方面,这三大手段相辅相存,推动着整个社会的科学前进。但是多年来在力学学科中这些手段的应用往往是独立的,至多同时进行,互相检验。随着近代科学技术发展,近年来作为科学研究方法将这三大手段互相结合、渗透已是一种可以预见的趋 An engineering mechanics analysis and research methods, like other natural sciences, can be summarized into three aspects: scientific experiments, theoretical analysis, and numerical calculations. These three methods complement each other and promote the scientific advancement of the entire society. However, the application of these methods in the discipline of mechanics over the years has often been independent, at most at the same time, and mutual tests. With the development of modern science and technology, it has been a predictable trend to combine and infiltrate these three methods as scientific research methods in recent years.
