According to HMH, it is 13, and in real life it falls within the range 0.5<τwσw<0.8 for ductile materials.
None of the criteria analysed can be applied to estimate the fatigue life under non-proportional loadings for materials that are sensitive to non-proportional loads. 3.

According to uncertainty of the design parameters for large span truss of installing wave-maker, in order to avoid the waste of materials,the truss is analyzed based on the finite element analysis software ANSYS to find out its weaknesses and various parts of the deformation.
It follows that the experience design of the truss is conservative, big and bulky and increases unnecessary weight and wastes the materials of rectangular steel pipes.

It can be seen that element movement is rigid movement, and normal and shear relative displacement reflect deformation (continuum) and interaction (non-continuum) of materials, These equations of above include motion (equations(1)-(2)), constitutive equation (equation(3), or(4)) and geometric equations((5),-(6)) , which constitute basic equations of distinct element method.
