Apart from building structure type, there are other factors that influent structure capacity, for instance, strength of main structure materials, crack situations of components, various bending, twist deformation and integral structure displacement.
Therefore, the influential factors are: surface cracks, main materials strength, structure types, deformation and displacement

In recent decades especially the extrusion of materials with low density, such as aluminum or magnesium, became more interesting for the industry to reduce the weight of the components.
In 1988, Akeret noted that die design and die correction is more an art than a science-based technology.
During optimization another material (Material-2) was defined which represents die material with an extremely high density and viscosity to prevent material flow.
The type of design variable is discrete; it can only be changed from Material-1 to Material-2.

Introduction A wide variety of polymeric materials, either biodegradable or non-biodegradable but biocompatible can be used as drug delivery matrices, and the choice of polymer is often dictated by the requirements of the specific application[1].
Electrospinning had earned the interest of many fields over the past few years, due to it capability of preparing materials at a nano-meter scale in a simple and straightforward process [2].
Meanwhile, its terminal group was supposed to react with monomer with double- bond structure, such NVP to prepare functional materials.
UPM could not be electrospun directly because of a little molecular materials, so poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) was used to improve the spinning-ability of the UPM.

Because of natural disasters, increasing population and urbanization, great amounts of waste plastic materials are produced.
It also helps to conserve natural resource because most of the polymer materials are made from oil and gas.
It combines the versatility and shape-making capability of plastic injection molding with the materials flexibility of powder metallurgy [3].

Composition of Paste-like Backfill Material Paste-like backfill material mainly includes cementitious material and aggregate.
Cementitious materials select paste-like cementitious material.
The choose of aggregate should adapt to local conditions, turn the waste into profit and select cheap or waste materials to meet the premise requirements of backfill for reducing the filling cost.
