For dry rubber, the solid rubber and other materials (for example, softeners, fillers, pigments for color, vulcanizing agents, and additives) have to be mixed together.
The materials science community broadly acknowledges the important effects of processing, dispersion and interface effects on the properties of a nanocomposite material.
Materials and Methods 2.1 Materials The Styrene Butadiene Rubber (SBR) used in this study was supplied by B.P.Chemicals, Mumbai.
Both types of interaction contribute to the reinforcement of polymeric materials.
The formation of chemical bonds in filling materials generates many of their physical properties.

Material constitutive relationship used mohr-coulomb model, simulating process of tunnel of excavation and support, researching and stimulating surface subsidence.
The process of excavating underdrain involved in increasing and decreasing of materials, take advantage of the ADINA(Element Birth/Death), and it was very convenient of achieving numerical simulation of process of excavating underdrain.the software of ADINA provides function of Element Birth/Death,it is in possess of many convenient that it is engineering definition,operating convenient and the fast of calculating velocity and so on. meanwhile it is able to simulate different scheme of constructing,by contrast of simulating different constructed schemes,select optimum schemes of constructing.

Steel materials and non-ferrous materials [M].

This method is a promising cutting technique especially in cutting difficult-to-cut materials, weak stiffness parts and high precision components.
So significant advantages of UEVC were obtained in lots of works with intermittent cutting as below: extending the tool life [3, 4], improving surface finish and form accuracy [5], enabling the use of diamond tools for cutting ferrous materials [5], and improving cutting stability [6].
The differences were mainly caused by the differences between the real materials and the ideal model.

Abstract: The current study is presented into the investigation of the application of ultrasonic vibration on the lower punch during compaction process of powder metallurgy material.
In many recent studies of the application of ultrasonic vibration have been extended into the compation of powder material [4, 5].
In a few previous studies [5, 6] have designed and tested the ultrasonic compaction tools for powder magnetic material.
