Özet

The governing equations of cylindrical isotropic helical springs loaded axially are extended to the study of free vibration of such helices made of composite materials. Stiffness method is used based on the first order shear deformation theory. A helical element has six degrees of freedom at each node, three translations and three rotations. The element stiffness matrix is obtained exactly based on the both complementary functions and the transfer matrix methods.
