Damage and fracture evaluation of granular composite materials by digital image correlation method

This paper presents the applications of digital image correlation technique to the mesoscopic damage and fracture study of some granular based composite materials including steelfiber reinforced concrete, sandstone and crystal-polymer composite. The deformation fields of the composite materials resulted from stress localization were obtained by the correlation computation of the surface images with loading steps and thus the related damage prediction and fracture parameters were evaluated. The correlation searching could be performed either directly based on the gray levels of the digital images or from the wavelet transform (WT) coefficients of the transform spectrum. The latter was developed by the authors and showed higher resolution and sensitivity to the singularity detection. Because the displacement components came from the rough surfaces of the composite materials without any coats of gratings or fringes of optical interferometry, both surface profiles and the deformation fields of the composites were visualized which was helpful to compare each other to analyze the damage of those heterogeneous materials.

小议我院公文写作的数字用法

公文中用数字来介绍情况、说明问题等非常简明、准确。本文通过引用国家的相关规定，结合我院(中国工程物理研究院)公文的实践写作，参照大量公文，对公文的数字用法进行一定的探讨，进一步规范我院公文数字用法。     

韧性金属裂纹尖端损伤区内应变场测量——数字散斑相关法应用

本文用数字散斑相关方法测量了五种不同幂硬化指数韧性金属材料(铝和铜),双边裂纹尖端细观区域内应变场.对所得结果用韧性损伤模型进行了分析.在此法中以金属自然表面结构为散斑场,不同加载状态的散斑场进行比较,得到相对变形与应变.图象之间相关性 C 是变形参数或是位移及其导数的泛函.使其相关性 C 取最大值的试凑变形即为其真实变形场.这一方法在细观测量中应用得到满意的结果.

生物质裂解产物的制备及HPLC检测其成分的虚拟仿真实验开发

In order to improve university laboratory teaching and practical education under the background of information technology, as well as overcome the difficulty for practical training, develop a virtual simulation experiment platform for rapid pyrolysis of natal materials and high-performance liquid chromatographic (HPLC) detection of its components. The experiment integrates the actual operation process of the plant to produce cleaved products by rapid pyrolysis of biomass with HPLC detection. The virtual experiment is divided into biomass sample pretreatment, rapid biomass pyrolysis, bio-oil extraction, and HPLC determination of complex components, making the biomass cleavage workshop "real" through simulation. This virtual simulation experiment fully integrates the utilization of biomass resources and basic chemistry courses (such as organic chemistry, instrumental analysis, chemical engineering principles, etc.), which are widely involved in agricultural and forestry majors with advantageous characteristics value.

简单1维数字流形的积空间中数字复叠的笛卡尔积的Deck变换群

首先提出了简单1维数字流形的概念,接着研究了简单1维数字流形的具有C-相容邻接关系的笛卡尔积空间中的数字图像.进一步,为了研究数字复叠的笛卡尔积的Deck变换群,利用半径2-(k_(i2),k_(i1))-局部同胚的性质来体现数字复叠的笛卡尔积的Deck变换群在从数字拓扑的角度来比较数字积空间时的优势.此外,通过强调C-相容的必要性修正了文献(Han S E.Comparison among digital fundamental groups and its applications[J].Information Sciences,2008,178(8):2091-2104)中的一个错误.利用本文的方法,可以从本质上区分数字积图像,从而使得数字图像的研究内容更加丰富.
