The material properties of the whole system are shown in table 2.
The stiffness value of rolling bearing is difficulty to be sure through theoretical calculation because it is related to bearing materials, shape and other factors, the reference estimates value take ==4×106N/m [5] , the bearing can be simplified by the unit COMBIN14 which is dedicated to the simulation of spring damper.

However paper [4] pointed out that the plasticity had great influence on the opening process of thermal fatigue cracks of the material.
The material researched by this paper is ZL702A, its plasticity can be revealed by multi-linear hardening model [5].
When the squeeze stress in the model is over the yield point of the material, plastic deformation occurs.

Preface The presented special issue is dedicated to the recent achievements in materials science and materials processing technologies used in modern mechanical engineering.
Here are investigated the lubrication features in the journal-bearing systems and induction-treated linear guides in the transmission elements, fatigue crack propagation in aluminium alloy under four-point bending and mechanism of multi-particle erosion of the iron target.
The next chapter contains articles on materials and technologies used in opto- and microelectronics.

For architectural impression the roof is made of unusual materials and complex structures thus cannot be designed with traditional guidelines.
The goal of using DSS is to facilitate and simplify the range of possible materials and structures, to assist and expedite finding the optimal version and to reduce the likelihood of design flaws.
In addition to eco-efficiency in production, transportation, and energy consumption of buildings, we hold it to be important to reduce the amount of materials used to a necessary minimum. [1] To achieve this all materials should be used at places where their specific characteristics prevail most effectively.
Introduction The range of building materials and skills needed to design building structures has broadened amazingly.
