Overall elastic-plastic stability behavior of cable-stayed ultra-high strength steel (660MPa) column with welded I-section is studied by geometric and material nonlinear FEM of software ANSYS.
FEM model of cable-stayed ultra high strength steel (660MPa ) column of welded I-section is established here and influences of slenderness ratio of central column and cable’s pre-tension on overall elastic-plastic stability capacity and mid-span deflection are computed by geometric and material nonlinear FEM in consideration of initial imperfection and cross-section residual stresses, and the results are studied in detail.

Industrial waste poses by far the biggest problem because of its nature and the vast variety of materials that have to be handled.
Raw materials: Green objectives call for minimize the use of materials whose acquisition is environmentally damaging and maximize the use of recycled materials and renewable resources.
Recycled materials are then transported to industries where make the materials valuable.
In addition, hazardous materials should be collected and transported safely.

Introduction Biodegradable macromolecule materials[1-3], due to having fine mechanical properties, processed properties and biodegradation, such as poly(lactic acid), poly (butylene succinate), poly (caprolactone),were expected as the environmental macromolecule materials which can be the most hopeful substitute of common plastic ,such as polyethylene and polypropylene[4-5][7].
In order to produce the degradation materials which can be fit to different area environment, we should carry out researches which can control degradation speed of the materials structure composition.

Materials and Method The three types of TWB that were analysed are presented synthetically in fig.1., that presents a circular blank realised through the welding of a disk-shaped part and a ring-shaped part, each made of steel with another thickness.
In the flange area, there is a thickening of the material, with a maximal value of 14%.
In particular, there need to be studied problems related to material failure criteria, design of the technological process and its control, as well as other details related to the deep-drawing of welded parts made of the same material but of different thicknesses but also of sheets made of different materials in order to achieve, on certain part areas, for example a higher wear resistance.

Introduction Selective laser sintering (SLS) process, a widely used rapid prototyping (RP) method forms parts directly from CAD data by fusing powdered materials using a laser source.
SLS uses a wide range of materials in powder form.
Materials and processing Laser sintering of the specimens were carried out using DTM SLS 2500 plus machine.
