In the later research work, the method provided can be applied simulation process by changing the process parameters for numerical simulation, so as to enhance the efficiency of double-metal composite seamless trial, avoiding the waste of materials and time.
The materials was made of external tube carbon steel Q235, which the Elastic modulus was 210GPa, Poisson's ratio was 0.3 and internal tube SUS316 stainless steel, which the Elastic modulus was 196GPa, Poisson's ratio was 0.3.
The material model was obtained by using the experimental material's true stress-strain curve.

The surface segregation in bulk materials has been reasonably well understood in the earlier thermodynamics work by Gibbs [5].
The size dependence of surface segregation and eventual phase separation may result in size-dependent properties of nanostructured materials.

In UK, every year around 70 million tons of C&D materials and soil ended up as waste.
Regulated by the Construction and Planning Agency (CPA), there materials can be highly reused and were useful.
Its by-products used as construction materials included tiles, heat-insulation bricks, ceramic tiles, and pipes.
As a result of asbestos by-products being replaced by other legal materials, the discharge of asbestos-waste was increasing.

Introduction GFRP has superior mechanical properties compared to previous structural materials and its application is now wide spreading from the daily supplies to the structural membership in hostile environments.
In this research, tensile test after water immersion and creep test under water environment was conducted to reproduce SCC in GFRP and to investigate the degradation in the material properties of GFRP.
