The instability and non-linear dynamics of a slender rotating shaft with a rigid disk at the mid-span are analyzed. The shaft is simply supported at both ends and is made of ...

For the spatially coupled stability analysis of thin-walled composite beam with symmetric and non-symmetric laminations, the element stiffness matrix is presented using the ...

We study a system of two complex ordinary differential equations with D4 symmetry describing the effects of the symmetry breaking O(2) to D4 on an interaction between Fourier ...

During the last three years the authors of this paper have been using Mathematica to develop symbolic computing tools that, at their present stage of development, allow to: ...
