A triaxial test is an important experimental method for geological materials including coal.
Since the invention of CT (computerized tomography), the inner defects and structures of materials have been detected widely by CT scanning.
Generally, the strength of geological materials agrees with Mohr-Coulomb Criterion that can be expressed as: (1) where C is cohesion, φ friction angle, the maximum principle stress σ1 equals to the compression strength, and the minimum principle stress σ3 equals to the confining pressure.
The white color indicates high-density material and the black indicates low-density material.

Introduction Metallic materials are still the most commonly used material for moving parts of mechanical assemblies.
In recent years, the area of coating materials has undergone significant evolution.
The ever-increasing market demand causes the development of new materials and ideas of coatings[2,3,5,6].
Although materials known for their natural self-lubricating properties are often used, modern deposited methods considerably extend their applicability [1].
Self-lubricating materials may vary widely in physical, chemical properties and structure which results in different classification methods.

Thus, these sulphides can be harvested in microelectronics as semiconductor materials.
The CuS/PVA diffraction pattern contains peaks of matrix materials between the humps 15o and 40o [14].

This causes rapid CT blade material degradation resulting in premature failures which are challenging to predict.
Material properties captured in Table 1 were then assigned to elements.
Heat transfer by convection causes differential temperature distribution which results to induction of thermal stresses on the material as illustrated in Fig. 4.
(8) Where is the creep strain rate, is the stress in (MPa), is creep strain, is time in (hours), is temperature in (), , , are material constants.

New materials such as ultra-high performance fibre concrete (UHPFC) could be cost-effective structuralengineering solutions.
In Australia, an example of this material available commercially is Ductal® by VSL.
The excellent mechanical characteristics and high density of UHPFC (Fig.1) make it an ideal material for resisting blast effects.

Nevertheless few of them report real material parameters and in any case the computational time makes them unviable for any industrial simulation process.
However, experimental deviations in copper [4] and other materials showed that a multiple peak behavior could refine an initial grain size, thereby suggesting the need for an improved criterion.
Other models that do predict multiple peak DRX do not use real materials.
