Abstract
Finite Element Method is used to analyze the concentric composite material shaft subjected to torsion. Isoparametric circular ring element has been formulated to solve the one-dimensional problem. An intermaterial element at the interface has been developed to accomodate the changing modulus of rigidity.
Solutions of Prandtl's stress functions are used to compute shear stresses and torque in the composite shaft. Results of torque of the composite shaft are established using convergence tests of homogeneous solid and hollow shafts. Good agreement with classical solutions are obtained for homogeneous solid and hollow shafts.
A Torsional Concentric Composite Chart has been developed showing the relationship between dimensionless torque, shear modulus ratio( shear modulus of inner material G1 to the outer material G2) and radius ratio( radius of the interface to the outer radius of the shaft).
