弹塑性力学的方法在解决实际问题上是不能与有限元法相提并论的。所以，...理论只能是解析的，而有限元法只不过是一种现在应用得很成功的技术手段而已-Elastic-plastic mechanics, in solving practical problems are not comparable with the finite element method. Therefore, the ... theory can only be resolved, and the finite element method is only a very successful application of technology now means nothing
