It also has mixed formulation capability for simulating deformations of nearly incompressible elastoplastic materials, and fully incompressible hyperelastic materials.
Then, for real materials with close pitting holes, the analysis of hydrostatic stress gradient should be related to this case, and not to a single pitting hole.

Separate collection of HHW on manual pipeline during selection of recyclable materials is not provided.
Collecting and recycling of household waste paint and varnish materials and household chemical residues, generated in the population, in Russia is not established.
For example in UK there are special Household Waste Recycling Centres that accept a long list of different paint and varnish materials [32].
The collection and processing of technical oils as a component of HHW in General is similar to waste paint and varnish materials.

The traditional fibres used within the cement-based materials are mostly made from steel, synthetic or glass (Bentur and Mindess, 2007).
Materials and specimens Ordinary Portland cement CEM I 42,5 N and quartz sand fraction of 0-4 mm were used for the production of mortars.

It is to strengthen design of tunnel water ecological implementation, including the optimization design of tunnel lining structure, lining the choice of waterproof materials, ecological environment protection under conditions of controlled drainage design.
In the drain near the tunnel entrance or in the pH value adjusting groove is provided with oil absorbing material to absorb oil of the construction waste water.

Main reason for this is that chloride exists in BF raw material and fuel.
In order to suppress abnormal corrosion of the gas pipeline system, analysis and study on corrosion mechanism of bellow compensator of gas pipeline is carried out to improve material and structure of stainless steel bellow compensator.
Material of bellow compensator is improved to stainless steel Incoloy825, which can prevent corrosion due to chloride ion, instead of austenite stainless steel 316L (00Cr17Ni14Mo2); polyethylene resin anti-corrosion paint is sprayed at the inner wall of the gas pipeline to separate metal pipeline and acid corrosion medium in order to suppress abnormal corrosion.

Moreover, correct material properties have to be simulated to achieve realistically looking virtual objects.
A complex BRDF model that can properly calculate light reflection on the surface to accurately simulate the materials of the objects in the scene will be used.
To lower these risks, education sciences foster a close collaboration between theoretical teaching in the classroom and job training, namely hybrid or blended learning [12].

In order to completely change the survival situations of the poverty population in the mountainous area, many traditional villages have to relocate, and the entity bearing the material culture and spiritual culture with the original cultural characteristics will be no longer in existence.
For example, wax printing and embroidery in Miao nationality are the industries with the national features as well as the business development value, which meets the material needs of resettlement and also meet the spiritual culture needs.
The exchange of “information, material and energy” is made constantly among culture types and between the culture type and the environment.

The transmission electron microscopy (TEM) used for materials characterization is Haitachi h-8100.
According to the definition, penetration depth is the depth at which the light intensity inside material falls to 1/e (about 37%) of its original value.
