It is hereby declared that this report can be entirely my work, unless otherwise mentioned, and that most sources of details have been properly acknowledged and referenced. It is additionally declared that report have not previously recently been submitted, entirely or in part, as portion fulfillment of any component assessment necessity.
Composites have been completely very powerful in displacing the traditional components due to their higher level of specific properties, namely strength and stiffness. In recent years, a large amount of studies have led to the emergence of advanced multi-scale predictive capacities, potentially providing composite material and structural designers with enhanced know-how and understanding the behavior with the material program that could assistance to reduce the time passed between research stage and the industry-based implementations. Ridotto indentataion and nanoscratch tests are most favored techniques for the study of micromechanical properties of the Composite material for the surfaces. On this factor, FEM has been more successful in design and analysis in the Composite materials in the recent years. Various FEM types have been analyzed which gives approximation method to estimate the micromechanical properties from the composites as well as interphase homes. FEM has become very useful in developing a composite resin model that may analyzed micromechanical properties in assistance with nano-indentation and nano-scratch technique and is served to get the correlation of trial and error results together with the numerical approximation values. Through this study a finite element modeling aided nanoscratch measurement system will probably be developed and applied for quantitatively evaluating the micromechanical real estate of the composite resin material. The evaluation is founded on the nanoscratch test with the aid of nanoindentor as well as the optimal method will be controlled by limited element technique. Both SECOND and 3D finite aspect model of the composite materials to incorporate the microscopic nanoscratch mechanism will be developed. This development will be validated together with the nanoindentor ensure that you numerical, experimental and deductive results will be compared. Keywords: Nanoindentation, Nanoscratch test, Elastic-Plastic properties, Finite Element Technique.
