一、引言间接列式法又称为虚荷载法。为了利用无限域中单位集中力作用下的开尔文解作为基本解,间接列式法也是以无限域为基本体系,把我们要研究的域视为无限域中的某一部分来求解。利用基本解,我们可以求得无限域中任意分布的荷载所产生的应力状态。假 I. INTRODUCTION Indirect method is also called virtual load method. In order to make use of the Kelvin solution under the unit concentration effect in infinite domain as the basic solution, the indirect in-line method takes the infinite domain as the basic system and treats the domain we want to study as a part of the infinite domain. Using basic solutions, we can find the stress state generated by an arbitrary distributed load in an infinite field. false
