They still study the stress and deformation properties of pile-raft-subsoil under the ultimate load by designing a series of model test about single pile caps and group pile raft foundation pile.
Pile foundation model experiment Many scholars study the load transfer characteristics and the bearing deformation characteristics of the pile through the way of loading, the density of soil, the surface roughness of pile, grouting and other factors to with indoor model test.
Conclusion Field test is the most effective way to study the pile foundation, but because of the disadvantages such as test inputs, long cycle and interference factors, the indoor test become the commonly used method to reveal the working properties of the prototype pile.
However, there are many interference factors, such as large investment, long cycle, difficult in setting test instrument, and no repetitive interference.
The pile raft foundation under the ultimate load combination properties for indoor model test research [J].

On the Relationship between Structural-Elastic Properties of Co-Zn Ferrites at 300 K Kunal B.
The density of any material depends upon two factors, the intrinsic mass of the particles (i.e. mean atomic weight), and the closeness of packing (i.e. mean atomic volume).
These factors are not taken into account in presently applied approaches that in fact lead to the observed difference in the magnitude of elastic moduli.

The subsequent phase interaction mechanisms are quite complex and have direct effects on the flow and final micro-structure distribution of the cast part and thus, without any doubt, on its mechanical properties.
But any little variation in the process parameters will affect the next filling.
The power law model is not able to reproduce the pressure distribution in the mold which means that it does not replicate entirely the physical properties of the metallic slurry.
For the industry, a homogeneous distribution of the solid particles is preferred in order to maximize the structural and fatigue properties.
In a solidifying semi-solid flow, many factors can affect the particles size and shape.

Apparently, the presence of defect in the initial state showed direct influence on properties like lower tensile strength.
Suitable heat treatment of the material should be used to remove undesirable factors such as internal stress or heterogeneity.
Even though there are regions that are affected more than other the deformation occurs in whole sample.

It has been shown that the starch-abaca green composites can be biodegraded faster than neat starch resin [8], and that some kinds of the green composites have acceptable mechanical properties comparable to those of GFRP [8].
It should be noted that the natural fiber composites have not only better mechanical performance [4,6,7] but also interesting functionalities such as biodegradability [8] and thermal insulation property [5,9,10].
However, the detailed information on the micro-fracture behavior of the green composites is still lacking, because there are many complicated factors affecting the fracture behavior of the green composites; such as fiber fracture, debonding and matrix cracking.
It is therefore suggested that the amount of pre-damage affect the mechanical performance of the natural fiber-reinforced composites.

It affects the quality of the appearance of the bumper and may affect the assembly size and using performance.
The main factors for the warping of the plastic products are: (1) Plastics and mold material; (2)Product structure, mold structure, mold strength, machining accuracy and surface roughness; (3) process parameters of injection forming[10,11].
Material CO/0949, which is similar to ABP-0948 on physical properties, was chosen in numerical simulation.
Conclusions (1)Based on the single factor, the effect of process parameters on warpage were analyzed by numerical simulation.The result shows that various factors have different effects on warpage.
Packing pressure is a remarkable effective factor.

The Abrasive Properties of Coal Power Plants Ash and Slag Materials Yury V.
These properties must be considered to ensure durable trouble-free operation of thermal power plants.
On the other hand, these properties can be used when planning measures for ash and slag material disposal.
But over time, coatings lose their properties, integrity, and need to be updated.
Abrasive properties of ASM are associated with their physicochemical properties and formation features.
