Stereovision measurements on evaluating the modulus of elasticity of wood by compression tests parallel to the grain

In this work, the evaluation of the longitudinal modulus of elasticity (EL) of maritime pine (Pinus pinaster Ait.) was investigated by means of compression tests parallel to the grain. Strain data was collected by digital image correlation (DIC) and compared with results from glued strain gauges. The DIC method provided similar results compared to the strain gauge measurements, but with reduced scatter due to higher gauge area, making the...
