Compression Test based on Piston Material 175-piston material is aluminum-silicon alloy, with the piston diameter as 75mm and height as 70mm.
This compression test is performed by microprocessor control universal material testing machine on the basis of the 175-piston.
According to the aforementioned experimental result we can arrive at the conclusion that the corresponding strains of the piston aluminum-alloy material are respectively 0.00091 and 0.0029 when the stresses reach 62Mpa and 180Mpa.

Preface A single CFST column can combine steel tube and concrete effectively, and develop the two material properties fully, thus gain the extensive favor in engineering, but when the load is eccentric or the slenderness ratio of component is big, a single CFST column is hard to develop its optimal property.
The Combined Material Poisson’s Ratio of Column Steel Tubes. the relationship curves of column tubular sectional load-combined material Poisson’s ratio of specimen is shown in Fig.9.
In later stressed phase, the combined material Poisson’s ratio begins linear ascend until failure.

A subclass of these materials is referred to as intermediate valence fluctuating or inter configuration fluctuating compounds and sometimes as mixed valence or mixed configuration compounds [1-7].
They form a very interesting group of materials in which many characteristic phenomena related to their electronic properties are observed.

Introduction With the development of the science and technology, the KDP single crystal plays a very important role in many types of key equipments, especially in the ICF( solid laser actuators and intense laser weapons.
More and more materials of KDP crystal are removed in brittle mode when the depth of cut increases gradually.
As shown in Fig. 9, when the cutting speed is less than 700m/min surface roughness increases with the cutting speed, because KDP crystal is soft and brittle material, and some built-ups will adherence on the rake face with the cutting speed increasing.
