Abstract
The knowledge of crack driving forces such as energy release rate and stress intensity factors is very important in the assessment of the reliability of timber structures. This work deals with static and creep fracture tests in opening mode crack growth. They are performed in climatic chamber, which allows reproducing the real environment effects on the cracking of Double Cantilever Beam specimens machined in Douglas and White Fir species. The evolutions of the crack length are posted versus time. The aim of this work is to compare the obtained experimental results with numerical tools given by a finite element model. The numerical model is based on a new analytical formulation of the A-integral, generalized to viscoelastic orthotropic material, which allows taking into account the effect of thermal and hydric loads in the cracking process.
