ABSTRACT:
A finite element study is made for the analysis of effect of fibre orientation on natural frequency (?) 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.
