Assume that the single stage supply chain nodes as a producer (core enterprise) and a raw materials suppliers, manufacturers and raw materials suppliers sign a contract ,form a enterprise alliance.
The core enterprise sent an order to the raw materials supplier, the material supplier provide product to core enterprise. 
The raw materials supplier decide how many products to deliver to the core enterprise in pursuit of the goal of profit maximization.
the mathematical model is established to determine the core enterprise's optimal order quantity and raw materials supplier's optimal production plan

The spatial variation of material parameters of the FGM can be arbitrary.
Introduction The mechanical properties of functionally graded materials (FGM) are continuously varying in position.
An alternative method to the very established and widely applied FEM is the boundary element method (BEM), which has been proven to be highly accurate and efficient for dynamic crack analysis of homogeneous and linear elastic materials [14-16].

From the results of researches on building collapse in Nigeria, substandard materials have been identified as major causes of reinforced concrete structural failure.
On the other hand inferior or substandard materials or workmanship can evidently depreciate the structural integrity thereby rendering it unreliable to resist the ultimate and service loading challenges.
Materials and Methods Field survey and experimental investigations were employed in this study.

The sensor type (MatScan) is acceptable for this type of dynamic load Mechanical tests (Tensile test and Fatigue test).The material used for the lamination forthe above knee prosthetic socket is a composite material made of a number of layers and as follows: 4.perlon, 2 fibres carbon and 4 perlons.This materials were tested to find the mechanical properties through tensile and fatigue tests.Acomputer numeric control (CNC) machine was used to cut and fabricate the specimens according to ASTM D638 type 4 [40].The specimens fatigue properties were found by testing the no. of cycles vs. the stress applied to the material used and obtained its (S vs. no. of cycles) graph, with the aid of a (HSM20) fatigue testing apparatus.
From this curve, the stress endurance limit was found 34.5 MPafor the composite material that was used.

The teachers can also give students some assignments on the text and ask them to surf the Internet to find out the relevant materials.
In the traditional teaching way, students are confined to the same textbooks and workbooks, and they have difficulty in getting extracurricular materials, especially some scientific advances which they are interested in.
Furthermore, students are encouraged to provide new relevant materials on the web, and the top-ten providers have been listed.
