Moreover, this paper makes an effort in incorporating theCosserat theory in the VCFEM for the elastic-plastic analysis of heterogeneous materialsbased on the PVP. The chapters are divided as follows: In Chapter 1, the author summarizes the study on the equivalent mechanics properties ofheterogeneous materials (including the development of the universal relationship which isirrelevant to the micro structure, the discussion of the limitations of the effective moduli, thecomputation of the effective properties of heterogeneous materials with the micromechanicsmethod and the FEM, and the equivalence of the heterogeneous micropolar materials) and thepresentation, the evolution, the corresponding numerical studies of the Cosserat model and itsapplications in engineering.
本文基于参数变分原理,构建了Cosserat体弹塑性有限元分析模型并用于求解应力集中和应变局部化问题;利用Voronoi有限元法提出了适用于非均质材料宏观弹塑性性能计算的参数二次规划算法;进一步将Cosserat模型应用到Voronoi有限元法中,提出了基于Cosserat理论的Voronoi杂交有限元法,并采用参数变分原理进行新模型的分析计算。

The result shows that B combines with N prior to Al at high temperature and brings about coarse particles of BN (about 900 nm), which effectively reduces the amount of fine and dispersive AlN particles, and BN precipitate clinging to MnS precipitation coarsens MnS particles, the pinning of austenite grain boundary is alleviated and the grain growth of ferrite is suppressed.
结果表明高温时B优先于Al与N结合生成粗大的BN粒子(约900 nm),有效降低了热轧过程细小而弥散的AlN析出量,同时BN依附MnS析出而粗化MnS粒子,减弱了细小弥散析出粒子对奥氏体晶界钉扎以及相变后铁素体晶粒长大的抑制作用。

Results Following orchiectomy 7d,the amount of CGRP-immunoreactive nerve fibers in the AP of the rat increased significantly, with the tortuous varicose fibers more densely distributed than that of NOR and the amount of varicosities increased significantly, while the thick fibers were more thicker than that of NOR,and many thin fibers were sent out from the thick fibers, and the varicosities were more larger.
结果 睾丸摘除7d后,大鼠垂体前叶CGRP免疫反应神经纤维发生了显著变化,表现为膨体型纤维较正常组稠密,分支增多,迂曲成片,盘绕成网,分布更加广泛,膨体数量显著增多;粗纤维较正常组粗,且发出许多迂曲盘绕的细纤维,膨体形态变大。t检验显示,OX组与NOR组垂体前叶内CGRP免疫反应神经纤维的平均面积密度差异显著,OX+V与NOR组差异显著。

The authors sug-gest that the decreased density of BDNF positive products in lamina II on the 3rd and 6th day was related with the degenerationof the nerve fibers and varicosities after section of the adjacent dorsal roots. On the 12th day, the remaining L6 dorsal roots un-derwent collateral sprouting compensatoryly and reestablished functional connection with target neurons.
