【摘要】：空間滑動面強(qiáng)度準(zhǔn)則(SMP準(zhǔn)則)根據(jù)實體空間的SMP平面上應(yīng)力狀態(tài)判斷確定試樣是否破壞。該準(zhǔn)則在三軸壓縮和三軸拉伸情況下退化為Mohr Coulomb強(qiáng)度準(zhǔn)則。通過對實體單元的應(yīng)力狀態(tài)分析,討論了SMP平面的空間位置以及SMP平面上應(yīng)力狀態(tài),詳細(xì)分析了SMP平面上應(yīng)力狀態(tài)點在三向應(yīng)力莫爾圓中的圖解方法。
[Abstract]:The spatial slip surface strength criterion (SMP criterion) is used to determine whether the specimen is damaged or not according to the stress state on the SMP plane of the solid space. The criterion degenerates to Mohr / Coulomb strength criterion under triaxial compression and triaxial tension. Through the analysis of the stress state of the solid element, the spatial position of the SMP plane and the stress state on the SMP plane are discussed, and the graphic method of the stress state point on the SMP plane in the triaxial stress moire circle is analyzed in detail.
