In 3Dmax, UC-win/Road can read the maps successfully only when them being appended by the material editor, set the mapping mode by UVW map.
Built-in model editor can edit size, materials and properties of the building.
The contours of warning signs, prohibition sign and some mandatory signs like round or triangular, so that a fit black map must be attached to reproduction pattern, check in the process of adding "through the black part of the material" option, then it can show its special contour in the 3D road network.

If the internal forces exceed the ultimate strength of the material, the RC inner-supporting would be damaged.
The Damage-Plasticity Model of Concrete The key of finite element simulation is how to chose a appropriate constitutive model of material and material parameters.
Then material is into the plastic zone and hardening stage until stress reach .
Compared with the actual measured data, the material is elastic in the early stages of loading.

According to the actual production condition, the material of the plastic kakou was used PA66[5].
Weld 1ines are the two strands or more than two strands of material flow form the lines when they meet.
In actual production, product structure, plastic materials, mould design and forming technology all effect the deformation.
The research has been funded by natural science foundation research projects of high institutions in jiangsu province(06KJB460026).

Finally, other two kinds of abundant “solid waste materials” in the power plant, ashes and gypsum, have been concluded for many applications.
Additional beneficial reuse applications are structural fill (highway embankments), subbase fill (under paved highways), roller compacted concrete, permeable base for paving projects, stabilizer for in-place asphalt recycling, soil cement compacted for an interior floor surface, soil stabilization, land reclamation, agriculture fertilizer, and environmental protection materials.
It is an almost sand-like material that is sluiced from the bottom of the boilers.
