Roughness Effect on the Mechanical Properties of Ceramic Materials Measured from Nanoindentation Tests A.
alvaro.rico@urjc.es Keywords: Nanoindentation, Roughness effect, ISE, Ceramic materials.
Several problems arise when these equations are applied to ceramic materials.
The influence is more significant for very stiff and hard materials, where the indentation depth is rather small and the plastic deformation limited.

Molecular dynamics (MD) is a powerful method that can simulate the materials at atomic scale and it can be used to predict the performance and properties of a wide range of materials.
a) Epoxy Novolac structure b) Bisphenol-A Fig. 1 Structures of Bisphenol A and Novolac Epoxy All the MD calculations were performed by Materials Studio 5.5 (Accelrys Inc.).
The structure was built by Amorphous Cell module of Materials Studio, as shown in Fig.2.
The approach here is also expected to be successful for other materials with complex networks.

Mechanical properties of mineral powder materials depend on the rheology of the powder materials flowing such as repose angle, friction angle, adsorbability et al[4].
Materials The mineral powder samples used in the study were exploited from Yunnan, China.
The crystal shape of mineral powder materials is seen clearly with increasing amplification multiple.
As the repose angle increases，the fluidity of mineral powder materials is decreased.
