| | Summary: |
| | The paper presents a procedure for numerical modelling of the geometric
nonlinearity of a rod. The calculation of cross-sectional forces, displacements and
rotations of nodes was done by iterative methods on a deformed system. By the described
procedure, the equilibrium state is established in the finite position of the rod. In the
process of deformation, there is an increase in cross-sectional forces and deformation of
the rod. The presented calculation methods are used to model geometric nonlinearity with
constant and variable stiffness of the cross section of the rod. The calculations were done
numerically, and the results were controlled using the SCIA software package. Through
numerical examples, the calculation procedure was presented and the analysis of the
results was performed. |
