Fig. 7From: Flow deformation characteristics of African blackwood, Dalbergia melanoxylonStress and strain at flow-starting point. a Compressive stress at the flow-starting point (σf). b Compressive strain at the flow-starting point (ɛf). Means with the same letter (a, b, c) are not significantly different (Tukey–Kramer test, p < 0.01) (n = 5). Error bars represent standard deviationsBack to article page
