One of the powerful methods to measure material properties at basic element level of materials is nanoindentation, however, this method can be reliably used only to get information about elastic properties (e.g. according to method published in [4]).
On the other hand the classical mechanical testing, e.g. three-point bending (3pb) test enables to describe nonelastic material properties from the stress-strain diagram.Materials and methods Sample preparation.

Introduction Functionally graded materials (FGMs) are new inhomogeneous composites.
Compared with homogeneous materials, the variation of deformation and stress of FGM structures subjected to mechanical load and thermal load is more complex, and it has become an important key technical problems in engineering application.
Functionally graded materials and the material properties In this paper, Assuming that the FGM is composed with two materials, such as ceramic and metal.

Diatomite or diatomaceous earth (DE) is one of the materials which can be used as an adsorbent to treat waste water polluted with heavy metal ions.
Introduction Diatomaceous earth (DE) is used in many industrial fields: wastewater treatment, filtering, petroleum processing, cleaning product manufacture, manufacture of fire or heat resistant materials and additives for building materials, etc. [1-9].
Materials and Methods Raw DE from Lam Dong province was ground in ceramic ball mill for 30 min, demagnetized to remove iron, and passed through a 90 µm sieve.
The experiments were conducted at Materials Laboratory, Ho Chi Minh City University of Food Industry.
