| ABSTRACT The objective of this research is to develop a finite element model for the analysis of the dynamic as well as the static response of a compressor blade made of composite materials subjected to extension, transverse, and torsion loads. The equation of motion is derived based on the variation technique with the principle of the total potential energy of a laminated fiber reinforced structures with different fiber orientation angles. The formulation is based on the classical laminate theory and the warping effect is taken into consideration. A one dimensional linear isoperimetric element with Lagrange and hermit cubic shape function are used to model the axial and transverse deformation. A two end nodes and one intermediate node as well is implemented for modeling the torsion deformation. The bending – torsion and axial coupling are introduced in the stiffness and mass matrices. The obtained results of the present model are compared to the available finite element and analytical results of others investigators, a good agreement is generally obtained. | ||
