Brittle stress strain
WebActually, energy absorption (under tensile conditions) is (as a first approximation, depending on the actual application) given by the total surface under the tensile stress-strain curve. Brittle ... WebThe results show that this numerical approach can perfectly capture the general features of brittle materials including fracturing process, AE events as well as stress-strain curves. Furthermore, the local stress disturbance is analyzed and the crack initiation stress threshold is identified based on the AE events process and stress-strain curves.

WebApr 7, 2024 · After the stress reaches its peak, the stress first decreases and then increases as the strain increases. As the water content rate increases, the top of the second peak gradually decreases. The main reason for this phenomenon is that the increase in water content causes the rock to change from brittle to plastic.
