Fig. 5From: Relationship between crack propagation and the stress intensity factor in cutting parallel to the grain of hinoki (Chamaecyparis obtusa)Changes of stress intensity factor KI and the crack propagation lengths (Δa). a 40 µm and b 113 µm of depths of cut. A bar indicates the crack propagation length between two consecutive images and a black plot indicates KI at each travelled length of the cutting toolBack to article page
