Experimental Studies of Infrared Characteristics in the Deformation and Fracture of Engineering Solid materials subjected to external loading Yongjun Zhang1,2,a, Nianjie Ma3,b 1School of Civil Engineering, Qingdao Technological University, Qingdao 266033, China 2 State Key Laboratory for GeoMechanics and Deep Underground Engineering, China University of Mining and Technology, Xuzhou, 221008, China 3 Faculty of Resources and Safety Engineering, China University of Mining and Technology, Beijing, 100083, China azhangyj_bull@163.com, bnjma5959@126.com Keywords: Infrared radiation, Deformation, Fracture, Thermo-mechanical coupling, numerical simulation, Infrared omen Abstract.
The studies in recent years show that solid materials such as rock and concrete always have regular thermal infrared (TIR) characteristics when the solid samples are loaded, and the anomalous IR phenomena appear before samples failure.
The prospective method will be applied in the fields of mining engineering, underground engineering and side slope engineering.
The TIR radiation detection technology would be a prospective new technology in rock and mining engineering.

Application Progress and Vision of Biocereamics Utilized in Bone Tissue Engineering Liu Yi a BME College, Tianjin Medical University, Tianjin, China a Pisces_cream@163.com; Anjian630712@sina.com Key words: Bioceramic, Bone tissue engineering, HA, CPC, BG, application Abstract: From human bones to animal bones, from stainless steel to plastic, researchers have tried numerous types of materials to apply in the bone replacement for human-beings.
But deal to their limitation on fatigue, stability, mechanical strength and many other properties, almost all those past materials were superseded by bioceramics today, which perform not only those advantages possessed by the old materials, but also hydrophilic, biocompatibility, thus ensured them a promising future in the region of bone tissue engineering.
Good biocompatibility of bioceramic materials made them perfect artificial synthesize scaffold material for bone tissue engineering.

The forming process of composite materials The key technology of composite materials is to meet the product shape, size and surface quality of the premise, the reinforced material can be evenly distributed in a predetermined direction, and reduce the performance degradation, the base material to fully complete the curing reaction, the interface and the reinforced material with good, discharge of volatile gas, reduce product porosity.
From the fiber reinforced composite started by the military and engineering circles.
So the improvement of the process becomes the key to development process of advanced composite materials, the next step.

The cutting thickness and feed rate could be more than 3~5mm and 30mm/min respectively in a cutting, and realized high-efficient, low-cost processing of engineering ceramics.
The primary cutting zone, the main material removal area, bears the main cutting force, and materials in this zone broke into debris in large-scale.
Using axial turning to machining engineering ceramics, the axial force is the main cutting force, and normal force and tangential force are too small which can be ignored.
