The goal of this paper is to improve understanding of the mechanical behaviour of PMMA through the experimental results obtained by performing quasi-static uniaxial compression tests and confined quasi-oedometric compression tests. As expected, temperature and strain rate sensitivity change the mechanical behaviour of the material on hand. In particular, the yield stress strongly increases for low temperatures as well as for high strain rates. The effect of hydrostatic pressure is also analysed via quasi-oedometric tests.
