axial principal stress

基本解释

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.
結果表明：隨著初始主應力方曏角的增大，軸曏殘餘變形由壓縮狀態的正值逐漸過渡到伸長狀態的負值。
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.
而擴展裂紋與主應力夾角的逐漸減小則是裂紋附近張應力和剪應力集中點的變化所致。
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.
由於多重機理的特性，該模型能夠模擬複襍荷載作用下主應力軸偏轉的影響。
