The designer must overcome the strain
localisation resulting from the low work-hardening rate, which
is the intrinsic character of superplastic materials.
Fig. 5 shows the relationships between cumulative strain and stress for both materials.
This results from the intrinsic temperature dependence of yield strength with superplastic materials.

In the United State of America, the American Society for Testing and Materials (ASTM D 6751) standard exist for determining the quality of biodiesel and blends and ASTM D 6584 deals with free and total glyceride contents of biodiesel.
Materials and Methods Materials: Reference standard reagents used were solutions of glycerine, 500 mg/l; monoolein, 5,000 mg/l; 1,3-diolein, 5,000 mg/l; and triolein, 5,000 mg/l.
It is also possible that during the GC analysis, other materials may co-elute with the glycerol peaks due to the high temperature involved and falsely giving higher results than expected.

Introduction
For modelling a process chain to predict the final material properties, it is necessary to use
microstructural physics based models, since microstructure is the state variable of materials
properties.
It comprises a twofold integration, namely a horizontal connection of the processing steps and a vertical connection of the physical models of microstructure development to the engineering level.
For Aluminum sheet the crystallographic texture was identified as microstructural key issue governing the resulting sheet properties.
The simulation started with tandem hot rolling and took the transfer slab material as input.
Furthermore the Deutsche Forschungsgemeinschaft (DFG) is gratefully acknowledged for providing funding through the collaborative research center SFB370 (Integral Materials Modelling).

Introduction
Sandwich constructions are commonly used in many kinds of engineering structures because of its outstanding rigidity, low specific weight, superior isolating qualities, excellent vibration characteristics, and good fatigue properties.
Recently, sandwich construction has become even more attractive to analysis the thermo-mechanical behaviour of advanced composite materials face sheets [1-7].
For both materials, Poisson’s ratio is assumed to be constant ν=0.3 (Fig 9).
