Abstract

A finite element study is made for the analysis of effect of fibre orientation on natural frequency (ω) for different mode shape in the simply supported and fixed rectangular fibrous composite plates with central circular hole. Study is carried out for three different D/A ratios (where D is hole diameter and A is plate width) to analysis the variation of natural frequency with respect to D/A ratio. The analytical treatment of such type of problem is very difficult; hence, finite element method is adopted for whole analysis. The finite element formulation is carried out in ANSYS package. The work is most appreciated in aerospace and marine industry where the study will provide the guidelines technique to designer for laminate configuration as per their requirements.

Keywords

Abstract

Aluminum metal matrix composite (MMC) is a kind of difficult to machine material. In general it is inefficient if conventional methods are used to machine it, with worse surface quality and serious wear of the cutting tool. This paper reports experimental investigations of the effect of machining parameters namely servo voltage (SV), pulse-on time (T_ON), pulse-off time (T_OFF) and wire feed rate (WF) on average cutting speed during wire electrical discharge machining (WEDM) of SiC_p/6061 Al metal matrix composite. Response surface methodology (RSM) has been used to plan and analyze the experiments. Voltage, pulse-off time and wire feed rate were found to have significant effect on average cutting speed.

Keywords
