Based on the unified strength theory with parabolic failure envelope, the nonlinear improved expression of the two-parameter twin shear unified criterion is presented. According to the cavity expansion theory, compaction effects of the tubular pile is studied. The elasto-plastic analysis solution of the stress field and displacement field of the soil around the pile are formulated. The results show...
BP neural network is easily trapped into the local minimum during the training process, which results that it can't get the optimal solution, even misjudging in device fault diagnosis. Directing to the above problems, a Hopfield-BP neural network fault diagnosis method was proposed, which combined Hopfield neural network, having the global optimal neural network computing ability, with the BP neural...
Directing to the low precision of single fault diagnosis method, a decision-level information fusion diagnosis system model was proposed to obtain more reliability and more accurate diagnosis, in which, the method based on the BP neural network was applied to the fault diagnosis firstly, and then the D-S evidence theory was utilized to partial fusions in diagnostic results, which was acquired in different...
By the nonlinear optimization theory, we predict the yield function of single BCC crystals in Hill's criterion form. Then we give a formula on the macroscopic yield function of a BCC polycrystal Ω under Sachs' model, where the volume average of the yield functions of all BCC crystallites in Ω is taken as the macroscopic yield function of the BCC polycrystal. In constructing the formula, we try to...
