Abstract
Shear moduli of wood were obtained with the shear block test, using the strain distribution measured with Digital Image Correlation (DIC). For comparison, the shear moduli were also measured by the torsion of rectangular bars, which afterward were processed to fabricate shear block specimens. A good agreement was found between the shear moduli obtained from the shear block and the torsion tests. The relation between the shear modulus and the nominal shear strength obtained from the shear block test showed good correlation (correlation coefficient of 0.59). Thus it is concluded that by applying the DIC the shear modulus can be determined from shear block test and the shear modulus can be used as an estimator of the nominal shear strength.
