Plasticflowfailure is mainly induced by building up of excess-static pore pressure.
塑性流动失稳破坏是由孔隙水压力的累积作用起主导作用;

The experimental results show that the failure of specimens will be either hydraulic fracturing or shearing plasticflow, it depends on the initial principal stress ratio.
研究结果表明,在不同起始主应力比条件下,试件可以表现为水力劈裂破坏,也可以为剪切塑流破坏。

The main reason of casing failure in most oilfields is the plasticflow in salt rock, gypsolyte and shale due to creep.
