The other one is material can be linear, isotropy or anisotropy, constant or relating with temperature in model analysis[1-3].
Rigid connection method is adopted between the supporting pillar with the main structure beam and strengthen beam of the supporting platform, and hinge node connection is adopted between corner steel constituting a stable system with edge support column and supporting pillar; All steel structure materials adopted in simulation are assumed to rational elastic materials; All steel structure component materials are assumed to linear elastic materials, and meet Hooke’s law, at the same time, in the simulation process Skin effect of steel plate is ignored.
To sum up, it can be seen from the analysis result statistics, all the calculated data is in the safety range of materials allowed, namely, the integral design that the coke powder tank supports platform can satisfy the requirement of production.

Introduction Poly(vinyl chloride)(PVC) is an extensively used thermoplastic material.
For this reason, the addition of thermal stabilizers was the only path way to solve this problem for PVC material[2].
Experimental Materials All materials were used as received.

The focus, however, has been shifted to the application of Ni-based materials.
Projects like MARCKO700 and COORETEC DE4 [1, 2] qualify different martensitic materials and Ni-based alloys (base materials and welded joints) for both, the application in steam turbines and boiler plants.

Based on a certain type of aircraft structure repair adhesive was studied, the curing temperature of aircraft structure repair commonly used adhesive process of high, long curing time, curing thermal stress problem, with epoxy resin as basic material, by adding elastic toughening Ding Jin g rubber, curing agent and silane coupling agent modification on Toughening of epoxy resin.
Although these adhesives have good adhesive strength and durability of the aluminum alloy strict surface treatment, but no strict surface treatment of metal and nonmetal materials, adhesive strength and durability are generally poor.
Therefore, the variation of strain measurement under the same load change with time layer on the anti stress relaxation proper tye valuation layer,the stress relaxation test piece shape as shown in Figure 1, is a constant stress cantilever beam, bonding reinforcing plate by the adhesive in the beam, rein force ment board for 0.3 mm thick carbon/ epoxy composite materials, metal plate of 3 mm thickness of 7075 aluminum alloy.
