As a kind of structural and functional material, the ceramics that is characterized by high-strength, heat resistance, and corrosion resistance, etc, has been extensively used in many fields such as industry, agriculture and science and technology [1].
However, ceramic materials are easy to produce cracks because of its brittleness and high strength, thereby easily leading to stress concentration in use.

Sandstorms' Influence and Prevention Countermeasures for Residents' Health in Baicheng City Hongyan Cui School of Geographical Sciences, Baicheng Normal College, Baicheng 137000, Jilin, China hongyancui@163.com Keywords: sandstorm, residents’ health, influence, prevention countermeasures, Baicheng city Abstract.
Among them, the sand storm refers to carrying storm formed by a large number of grains of sand blowing near ground; dust storm is a storm formed by a large number of dust and particle material involved in high altitude by the Strong wind.
But small particles in the adsorption of harmful material such as harmful gases, heavy metals, organic pollutants, when particles into the upper respiratory tract, these harmful material to the upper respiratory tract have irritation and corrosion effect, which ruined the respiratory defense system.
In all the public, we should take warning education of the deteriorating ecological environment, strengthen the propaganda of popular science knowledge about sandstorms and ecology, set up the concept of environmental priorities and prevention priorities, and minimize the hazard of the sandstorm to the lowest possible levels.

The wasted time, energy, and material impair the manufacturer's efficiency and competitiveness.
Modeling of Residually Stress-induced Distortion Due to Material Removal Finite element simulations were conducted utilizing the ABAQUS Finite Element Code.
The stresses in the remaining (active) elements were then used to determine distortion and the redistribution of original residual stress distributions in remaining materials [4].
