redistribution of stress meaning in Chinese

应力重分布
应力重新分布

As a result , shifting of the fundamental frequencies and redistribution of stress in the blade base possibly cause failure of the blade . a three - dimensional finite element model of a blade and its fir - tree attachments have been constructed and analyzed with taking into account of contact nonlinearity in the attachments and large deformation effect of the blade . the geometry mismatch was introduced into the finite element model by defining gaps between two contact surfaces in the attachments
分析结果表明叶根误差发生的位置对叶片弯曲振型的固有频率影响较大,对扭转振型影响较小;误差的大小对叶片各阶固有频率影响均较小,但对叶根应力分布有影响;比较发现,在计算固有频率时,将叶片在叶根处简单地处理成固支位移边界是不合理的。
At the same time , depended on the creep test of double - prestress composite structure which is just being observed , the calculation theory and method of the redistribution of stress of double - prestress composite structure is studied and some helpful reference for design and research of this new - type structure is offered in this thesis
同时本文结合正在观测中的二次预应力组合结构徐变试验，研究了二次预应力组合结构徐变应力重分布的计算理论和计算方法，为二次预应力组合结构这一新型结构的设计和研究提供了一些有益的参考。
