This paper presents a series of uniaxial compressive loading tests carried out on cylindrical samples of Indian bamboo, together with a stress strain model. The bamboo species Oxytenantera abyssinica, from the Congo Basin forest is used for these tests. The non-linear behavior of Indian bamboo may be attributed to two distinct mechanisms, plasticity and damage. These two mechanisms are described by the endochronic theory of plasticity and continuum damage mechanics. A dissipative model, taken into account plasticity and damage through various parameters is proposed. The parameters of the model are deduced from monotonic and cyclic uniaxial compressive tests. The proposed stress-strain modelis compared to the tests results and it can be found that the model fits well with experimental results.
