一问题的提出用试验方法求解弹性体空间应力问题——表面和内部,不仅是工程实际的需要,也是发展计算理论的需要。长期以来,结构模型试验(电测)只限于表面应力,实质上是平面应力的量测。内部空间应力问题似乎一直没有得到解决。国外,Allen 在五十年代、Rocha 和汤浅昭在六十年代,都曾提到结构模型试验不能量测内部应力。七十年代初期,Fumagalli 在其结构模型试验专著中仍然没有在这方面取得进展。国内在五十年代,有的单位曾先后研究过,但进展也是十分缓慢的。 Solving a problem using experimental methods to solve the problem of elastic body space stress - surface and internal, not only the actual needs of the project, but also the need for the development of computational theory. For a long time, the structural model test (electrical measurement) was limited to surface stress and was essentially a measure of plane stress. The problem of internal space stress never seems to be solved. Abroad, Allen in the 1950s, Rocha and Yuasa Asahiro mentioned in the 1960s that structural model tests did not measure internal stresses. In the early 1970s, Fumagalli still did not make progress in this area in his monograph on structural model testing. Domestically, in the 1950s, some units had studied successively, but the progress was also very slow.
