-Abstract
A finite element formulation is presented for modeling the dynamic as well as static response of a compressor blades subjected to extension, bending and torsional loads. The formulation is derived from the variational principle with the consideration for the total potential energy of the structure based on the classical lamination theory. The compressor blade is modeled as an advanced beam with idealized rectangular cross-section that takes the warping effect into consideration. The bending-torsion coupling is introduced in the stiffness and mass matrices. A one dimensional linear isoparametric element with hermit cubic shape function is used. A two end nodes and one intermediate node as well is implemented for the finite element formulation. A Matlab interactive code was developed to solve a blade with a multi action loads. The results obtained are compared to the available analytical and finite element results.
