Fig. 21From: Investigation of mechanical properties and elucidation of factors affecting wood-based structural panels under embedment stress with a circular dowel II: detailed observation for plywood and OSB using DIC and CT scanningRepresentative difference images exhibiting voided and densified areas. Red and blues areas are voided and densified areas, respectively. a Image of a strong axial layer in PW (ultimate difference (UD) of the third layer of PW-s with d = 5.2 mm). b Image of a weak axial layer in PW (UD of the fourth layer of PW-s with d = 5.2 mm). c Image of an outer layer in OSB (UD of the first layer of OSB-w with d = 12 mm). d Image of an inner layer in OSB (plasticity difference of the second layer of OSB-s with d = 12 mm)Back to article page
