New Method for Characterizing Interface Fracture Between Dissimilar Materials Junlong Peng1,a, Jiao Tang1,b, Zhenyu Ouyang*2,c ( * Corresponding Author) 1 Changsha University of Science & Technology, Changsha, Hunan, 410000, China 2 Southern Univerisity, Baton Rouge, LA, 70813, USA a bestengineer@163.com,b tangjiaoweirui20@126.com,c zhenyuouyang@hotmail.com Keywords: Cohesive zone model, Interfacial fracture, Hybrid joints, bi-material interface.
Bonded interfaces of two dissimilar materials, are quite common.
Therefore, the fracture behaviour of bi-material interface cracks attracted considerable attention in the recent years.Due to the different chemical, mechanical and thermal behaviors of materials, dissimilar materials joining presents challenges significantly different than similar materials joining..

Combining materials handling and stacking operations, this paper takes the fertilizer bags as the object and studies on the image processing method of the material stacking and segments the stacking image.
Introduction Materials handling and stacking is a common industrial and agricultural production operations.
The powder products such as cement, fertilizer, rice, flour, starch, feed, building materials, chemical raw materials, and metal products widely are used woven bags for packaging, and the production of these materials is very large.
There are some advantages by using robot load-unloading materials, such as gripping reliably, moving flexibly, placing neatly and so on.

With the surface materials of cold region buildings as the research object in this paper, a study on the changes in the color of surface materials in the cases of discoloration, fading and yellowing is made.
The causes of discoloration, fading and stains vary with materials.
The building materials in this area show different color attenuation from those in temperate regions.
Therefore, it is necessary to perform investigation into building materials and forecast color attenuation, based on which proper materials and methods can be selected. 2 Discoloration and Fading The use of plain colored materials and coatings mainly for protection more or less allows some change in appearance (color, luster, texture) [2].

Amongst which most of the researches were on the ESC electrode materials conducting polymers (using as the ESC electrode materials) have attracted much attention for their excellent specific capacitance, high conductive characteristics and low cost [3].
In order to overcome the disadvantage, carbon materials were used as electrode substrate materials.
Fig. 4c is the discharge curves of the ESC with these two electrode materials.

In other words, the production would emission less harmful gas and dust than other building materials.
Timber materials which are specific produced is one of the best waterproof building materials.
Chemical osmose process means that timber materials are measured by a certain concentration of fire retardant.

The production process of filtration materials and the character of light CaCO3 as pore-forming agent were described; For the selected raw materials, changed the ratio and aggregate granularity, the influence of ceramic aggregate content on the aperture, aperture distribution, porosity and bending strength of filtration materials and the influence of aperture distribution of aggregate on sample's capability have been revealed based on the XRD analysis, SEM observation and bending strength measurement of filtration materials; at the same time, the influence of sintering temperature on the porosity and bending strength of filtration materials was also studied.
The results show that the better filtration effect and better chemical durability, the higher bending strength (15MPa) of the synthetical filtration materials can be obtained when the content of aggregate, the particle size and the sintering temperature are respectively 50~55wt%, 150~180µm and 1205°C. 1 Foreword With the rapid development of material science, the position of ceramic materials in the modern technique is improved.
As functional materials, filtration materials was exploited earlier in convection technology(or thermal transmission and mass transfer technology), so filtration, separation, fixed carrier, heat insulation, temperature sensor and others have been studied and applied widely.
