“…It is observed from the results of the fracture toughness testing of Al6061graphite [15] and Al6063-SiC [16] that Al6061-graphite composite has more fracture toughness values. Different authors [15][16][17][18][19][20][21] studied the different methods of the finite element techniques to determine the mechanical/fracture behavior of the materials. Experimental techniques on prototype provide information concerning the structure in the pattern of the experiment only.…”

The main objective of the work is to study the fracture behavior of AA6061-graphite material using both experimental technique and finite element simulation by considering helicopter rotor blade as a case study. From the case study, it has been observed that the helicopter rotor blade, made of AA6061, has been failed at the threaded portion of the hole. Experimental fracture toughness is carried out using the compact tension specimens as per ASTM standard testing procedure. Modeling of compact tension specimens and the threaded portion of the bolt hole was utilized to analyze the fracture toughness using a simulation tool. From the results and the comparison, it is recommended to use AA6061-9wt% graphite material as a replacement of AA6061 in the application of main rotor blades of the helicopter.

Naturally accessible materials have recently become appealing to researchers and scientists due to their suitability as an ideal reinforcement for polymer composites reinforced with fiber. Low cost, relatively strong mechanical properties, qualities of non-abrasive and bio-degradability, exploited as a switch to the standard fiber. This research investigates the effect of areca fiber reinforcement of fracture load and fracture toughness. Epoxy resin used as a matrix material. Type I fracture hardness checks are conducted in a universal servo hydraulic control system. The findings revealed a significant improvement in fracture load values and durability of fracture with improved fibre content.

This paper considers the usage of Taguchi's contribution ratio as well as an adjusted Pareto diagram for determining the size of influential design factors in experimental design on output values in order to determine the best combination of input factors, as well as factors that can determine output. Two case studies that cover extreme examples are presented in that aim. The first case study examines one input workspace design distributed on tree experimental designs defining space coordinates. Every design has several output values that were measured. The second case study presents two experiments regarding injection of plastic molding process, with same input factors at parts which are different in material and dimensions with geometric deformations as output. It was shown that different experiments lead to different results, of which one is acceptable, while other is useless for further examinations. Accordingly, this paper gives guidelines how to use Taguchi's contribution ratio and Pareto diagram effectively in determination of influential factors in experiments.
