Based on a stress investigation of structural failures of the railway system in China, a new method to determine the stress is put forward to overcome the deficiency of conventional simulation and experiment methods. Through numerical simulation, the inference relation of the stress between various locations is obtained. Then, by experiment, some stresses in the whole structure are measured. Accordingly, other stresses are determined through the inference relation. Furthermore, all the stresses in the structure are obtained and the strength evaluation can be exactly carried out. Taking the cantilever beam and the cantilever device supporting the catenary for example, how to deduce the stress by this method is discussed.
