GTN

There is more error in simulating void growth under unaxisymmetry triaxial stress conditions using R-T model and GTN model.

用R-T模型、GTN模型模拟非轴对称三轴应力状态下材料微孔洞损伤演化有较大的误差。

It was reported that using the PEA protocol as the first choice for high-risk GTN, and had achieve good effect.

有报道使用PEA方案作为高危GTN的首选治疗方案，取得良好的疗效。
