The results show that the gabion meshes present good tensile characteristics in the event of the rupture of the meshes. The larger-diameter gabion mesh shows a better mechanical performance, and the mechanical performance of 80RE geogrid is superior to that of 70RE geogrid. The revised relationship curves between the tension per unit width and unit elongation also present elastic stage, yield stage and strength stage. The constraint deformation of reinforcement is influenced by factors such as secant modulus of materials, stress levels, and the length of reinforcement in active area and stable area.

When NiTi alloy was tensiled at 600 ℃ and at a lower strain rate, the dynamic recrystallization occurred. Without electric field the stress-strain curves were characterized by periodical undee graph, while under the electric field they presented steady state. When deformation under the electric field, both strain hardening and recrystallization take place simultaneously, thus the flow stress curves exhibits steady state.

NiTi合金高温拉伸变形过程中会发生动态再结晶，在应变速率较低时其应力-应变曲线呈周期性波浪形，在应变速率较高时其应力-应变曲线则呈现较平滑稳定的态势；施加电场作用时抑制了这种周期波浪形变化，使应力-应变曲线呈平滑稳态变化。
