Abstract A rod-chain model was used to study the dynamics of a tree stem. A numerical method is developed for simulating the mechanical behavior of a flexible tree stem. The motion of the flexible tree stem is determined under the resistance forces exerting on the tree crown. Flexible tree stem interaction with an elastic foundation and a forest machine is investigated as well. The numerical model is applied for calculating the impulse of force on the elastic foundation and the forest machine.
