Experimental Research on Temperature Field in Ultrasonic Assisted Grinding Engineering Ceramics Guofu Gao 1,2,a , Chuanshao Liu1,b, Bo Zhao 1,c , Feng Jiao 1 , and Qinghua Kong2 1 School of Mechanical and Power Engineering, Henan Polytechnic University, Jiaozuo, China 2 School of Mechanical Engineering, Tongji University, Shanghai, China a gaogf@hpu.edu.cn, blcs@hpu.edu.cn, czhaob@hpu.edu.cn Keywords: Temperature field, Ultrasonic grinding, Engineering ceramics Abstract.
As one of the key factors grinding heat has a significant effect on the ground surface quality in grinding engineering ceramics using diamond grinding wheel.
Differences between mechanical and physical performances of ceramic materials and grinding parameters have important influences on the surface temperature distribution.
Along with a wide range of application of hard-brittle materials such as engineering ceramics, glass and stone in the field of engineering and building, the analytic solution of the temperature field was of great interest in the process of hard-brittle material machining.
The theoretical analysis for the temperature field of hard-brittle materials was referenced the well-rounded heat source model for traditional metal grinding [8].

Based on these connections between engineering and key components of sustainable development, we can say that achieving sustainability in engineering becomes a critical issue to achieve [3].
These resources include water, materials, energy and others
This implies that the engineering processes and operations utilized must exhibit sustainable characteristics in terms of the operations and steps they involve, and the energy and materials they utilize
Taking into consideration these key requirements, the authors propose the fractal triangle of engineering sustainability, Fig.2.

To Identify the Qualities and Prices of the Materials or Equipments.
The costs of equipments and materials in construction projects has a large proportion of the total cost, accounting for about 70%, and they are also a major component of direct costs.That the quality of machineries and equipments, the selection of engineering materials, the inspection of products and so on, should all directly affect the progress and quality of construction, then affects the project cost.Therefore, engineering supervisor should assist the owner in purchasing equipment through bidding, to ensure the product quality; the certificates and test reports of equipments and materials should also be reviewed one by one; at the same time, they should strictly control the materials consumption according to the contract, and review the order lists of all materials, equipments and mechanical parts, to determine its reasonable formation of prices.
With this change that take direct order, the price of raw materials would be saved about 20%.
The information include that completion drawing, design change notification and on-site visa, hidden engineering and claims processing information, information on equipments and materials supplied by owner, information about specification, brand, price of materials, information on a variety of special craft, etc.
They take effective measures ,which in the aspects of the design drawing, bidding documents, construction contract, construction project measure, equipments and materials, payment procedures, engineering change, engineering claims, complete settlement and so on, to control the investment.

Introduction The Control of fracture and brittleness is one of key issues of development of engineering materials which are intrinsically brittle or extrinsically brittle due to detrimental effects associated with service condition and/or environment.
Now the grain boundary engineering has been widely accepted as a new approach to materials design and development of high performance structural and functional materials [8-10].
Quite recently the grain boundary engineering has been well evidenced to be so powerful to control intergranular fracture and brittleness of brittle polycrystalline structural materials and even for functional materials [6-8].
The State of the Art of Grain Boundary Engineering for Fracture Control 5.1 Grain Boundary Engineering for Brittle Materials Here we just briefly introduce our recent works on grain boundary engineering for fracture control in ceramics such as SiC [21] and alumina [22] which are normally very brittle, but of engineering importance.
