In this work, the determination of the longitudinal modulus of elasticity (EL) of maritime pine (Pinus Pinastar Ait.) wood was investigated by means of compression test parallel to the grain. The effect of parasitic end-effects (i.e., friction and damage) on the correct evaluation of the EL modulus was studied using parallelepiped wood specimens with different cross-section areas and lengths. The results from the data reduction conventionally applied to this test method were compared to values obtained from strain measurement provided by a full-field optical method (stereovision technique). The influence of the geometry of the specimen on the correct evaluation of the EL was assessed and discussed
