The results show that: when the stress triaxiality is low, the penny-shaped crack can lead to damage anistropy of a ductile material; and the variance of Lodes parameter will lead to the variance of the expanding rate and deformed shape of penny-shaped crack and sphere-shaped void.

进而对材料中同时含有币形微裂纹和球形微孔洞的情形作了数值模拟分析。计算结果表明：币形微裂纹的存在将导致低应力三轴度下韧性材料破坏的细观损伤呈现明显的各向异性；而Lode参数对微裂纹和微孔洞的长大和变形状态具有较大的影响。

However, if the Chinese people still look forward to establish a evergreen foundation emprise, the sustainable development society, the personal experience of public figures, and the publication and communion of consideration is the important prerequisite for.

但是，如果人们仍期待华人能够建立起基业常青的公司、可持续发展的社会，公众人物的个人经验、思考的公开与共享，是重要的前提。
