axial principal stress

基本解釋

The results show that: with the initial principal stress direction angle increases, the axial residual deformation from the compression state gradually transits to the elongation.
結(jié)果表明：隨著初始主應(yīng)力方向角的增大，軸向殘余變形由壓縮狀態(tài)的正值逐漸過渡到伸長(zhǎng)狀態(tài)的負(fù)值。
And that the angle between extending crack and principal axial stress decreases gradually is caused by the variation of tensile and shear stress focuses in the course of brittle formation.
而擴(kuò)展裂紋與主應(yīng)力夾角的逐漸減小則是裂紋附近張應(yīng)力和剪應(yīng)力集中點(diǎn)的變化所致。
The effect of rotation of principal stress axial directions and large shear displacement of sand in the earthquake induced liquefaction are taken into account at the same time in the model.
由于多重機(jī)理的特性，該模型能夠模擬復(fù)雜荷載作用下主應(yīng)力軸偏轉(zhuǎn)的影響。
