This project studies the scale-dependent deformation behavior of the metal matrix composite, the void nucleation and void growth mechanisms at the micron/submicron scale. The main results are:(1) In prophase, growth and coalescence of the void embedded in the graded matrix are analyzed in detailed;(2) Based on the infinite solid model containing a micro-void, coupling effects of the void shape and the void size on the void growth are studied carefully, the results show that it seems to exist a critical equivalent void radius, which is associated with the material length. When radius of a microvoid is close to or smaller than the critical void radius, the micro-void growth rate is essentially eliminated;(3) The coupling effects of the particle shape and size on the mesoscopic stress fields within the particle and matrix are also investigated by introducing the conception of inclusion/matrix interfacial energy. The results show that the stress concentration factors within the particle and on the matrix/particle interface are also strongly size-dependent,so the void nucleation mechanism is size-dependent.(4) By employing a specific orthogonal curve coordinate frame and a 'kernel function' conception, a 'unified method'solving the spheriodal and spherical void problems is suggested; by this unified method, size-dependent plastic potentials of the porous materials containing the spheriodal or spherical voids are obtained, which extend the traditional Gurson model for the spherical void and GLD model for the spheriodal voids to the micron scale.(5) Based on the RVE model containing the spheriodal or spherical particles, the influences of the particle shape and size on the size-dependent mechanical behavior of metal matrix composite are studied.
中文摘要:本项目对金属基复合材料在微细观尺度下的尺度相关变形行为、孔洞形核及长大的机理和模型进行了研究,取得了如下主要结果:1)在前期研究中,探讨了基体的梯度分布对孔洞长大和聚合的影响;2)基于含孔洞的无限大体模型,探讨了孔洞形状和孔洞尺寸对其长大的耦合作用,结果表明:可能存在一个与材料特征长度相关的临界孔洞尺寸,当椭球孔洞的等效半径小于临界孔洞半径时,孔洞的长大受到明显抑制;3)通过引入基体/夹杂界面能的概念,分析了夹杂尺寸、夹杂形状对材料细观应力场的耦合影响,结果表明:颗粒内部和界面上的应力集中因子强烈地依赖于夹杂的尺寸和形状,因此,孔洞的形核机理是尺寸相关的;4)采用一种特殊的正交曲线坐标系和引入"核函数"的概念,"统一"地得到了含椭球和球形孔洞的材料的尺寸相关塑性势,它将传统的Gurson球形孔洞模型和GLD椭球孔洞模型推广到微尺度范围;5)基于含椭球和球形夹杂的体胞模型,初步研究了夹杂形状、夹杂尺寸对金属基复合材料尺寸相关力学行为的影响。

Firstly, the stope vacancy was monitored using CMS, taking cavity measured data as foundation, cavity three-dimensional model of the stope opening was created using Surpac software and gain the stope three-dimensional configuration and the actual boundary accurately. Then, the stope designed model and ore-rock interface digital terrain model were established according to the stope design material. Finally, using ore-rock interface DTM to cut cavity model or through Boolean calculation among the models, ore remains, mining total volume, mullock, backfilling, pure ore and dilution rate of stope N3-4 were calculated accurately, thus the large-scale stope mining index visible calculation was realized effectively.
