Determination of the stress-strain curve in specimens of Scots pine for numerical simulation of defect free beams

The objective of this paper is to develop a twodimensional numerical model to simulate the response of Scots pine (Pinus sylvestris L.) defect free timber members in order to predict the behaviour of these members when subjected to external forces. For this purpose, data of the mechanical properties...

For this purpose, data of the mechanical properties of Scots pine were obtained by performing experimental tests on specimens.
