To improve properties of foam concrete microstructure is studied with the help of fractal theory, fractal dimension related to mechanical properties and thermal performance of foam concrete is calculated by MATLAB language program.
However, general low strength of foam concrete is seriously affecting its further promotion and application[1].
The relationship between microstructure and mechanical properties and thermal property of foam concrete is studied.

These factors prevent extensive applications of titanium alloys for making numerous products for which the favorable properties of titanium alloys are highly desired [5].
To obtain comparable mechanical properties as wrought alloys, PM Ti alloys should be fully densified and fully sintered, have fine and homogeneous microstructures and low content of impurities, especially O, N and C interstitial elements which can cause the mechanical properties of Ti alloys to deteriorate dramatically[6].

Based on the earthquake failure mechanism of high slope, this paper analyzes the impact factors on highway high slope seismic stability, and puts forward earthquake preventive measures for high slope.
As for which one plays a decisive role in two factors, depending on conditions.
Different types of slope failure, dominant factors are also different.
Surface water such as rainfall effect is, with rainfall infiltration, slope body weight increase and the mechanical properties decrease of slope potential slip surface or structure , at the same time, the pore water pressure increases between fracture surfaces , which is not conducive to slope stability.
Conclusions (1) Geological structure, rock and soil type, lithology, topography, hydrology geological condition and seismic load are main influence factors of high slope seismic stability

The mechanical properties of single-bolted steel-glulam-steel connection subjected to a load parallel to the grain have been studied.

This paper reviews the various influencing factors of the pressure distribution and also summarizes its simulation and prediction methods based on the sufficiently literature reading.
Granular goods of sand, gravel, crushed coal, cement and other powdered goods known as bulk whose physical properties were state between solids and liquids, were consist of the objects with relatively homogeneous particle.
Influence Factors Many studies showed that the pressure exert on compartment by bulk goods was mainly influenced by following factors: Physical and Mechanical Properties Shear Strength.
At present, the impact brought by this factor was considered by a vibrating densification coefficient. [1] Creep Property.
Besides FEM, the mechanical behavior of bulk is also studied through DEM(Discrete Element Method) by researchers from aviation, silo, railway and other fields.[1,14,15] Conclusions Above all, there are many factors influence the pressure of the sidewall of bulk carriage, and these factors will interact with each other, therefore the predication of the variable pressure is a rather complex scientific problem.

This research aims to study the effect of thermal aging on the morphology and mechanical properties of thermoplastic vulcanizates (TPVs) based on a mixture of natural rubber (NR) and polystyrene (PS).
The real cause of the rubber prices declining now is because the amount of production and demand for rubber is not balanced, therefore affecting the selling price.
The mixed materials are called Thermoplastic elastomer (TPE) and can be used to improve properties by doing dynamic vulcanizates (DVs), which is called thermoplastic vulcanizates (TPVs), the results of the dynamic vulcanization process improve mechanical properties and solvent tolerance and can be used at high temperatures [1, 2].
Furthermore, the results of sample mixing were prepared for testing the mechanical properties (tensile strength, elongation at break and impact resistance) and morphology.
