Brittle deformation is generally seen in

WebDeformation: a) is brittle when many chemical bonds are broken quickly and the rock pieces separate. b) produces changes in the shape and orientation of rock grains and rock layers. c) is a characteristic of mountain belts. d) may produce faults if brittle, and may produce folds if ductile. e) all of the above are true statements. WebApr 13, 2024 · The development of inelastic deformation of quasi-brittle materials is generally believed to begin at 60-70% peak force. The approximately symmetrical profiles on both sides of the slit were observed from the contour plot of the displacement; profiles began to merge at the notch tip, and as the load increased, local non-uniform …
