As examples, the critical loads of annular plates under the uniform radial pressure and shear forces are given.
作为算例,给出了环形板在中面均匀径向压力和剪切力作用下的临界载荷。

So a split-type shear box is adopted to conduct the in-situ shear test in order to make the stress on the shear plane uniform and ensure the shear stress to running through the center o.
The most important issue for the problem of uniform cross-section bar torsion is the calculation of shear stress on the boundary of cross-section, which is very difficult.
