type of force limiting device can be applied to spatial structure to meet the requirements of bearing bidirection axial forces, preventing progressive collapse and dissipating seismic energy. It also can be applied as a new type of buckling restrained brace and energy dissipation device. Key words: force limiting device; large displacement reversal loading test; low-cyclic loading test; equivalent......
: Based on the compression mechanism for analyzing the cavity expansion problem in soil under high stresses, generalized non-linear failure criterion and large strain and energy conservation in plastic... dissipation analysis method, in which the energy generated from cavity expansion is absorbed by the volume change and shear strain caused in soil. The factors of large strain and dilatation were considered......
Strain measurement of fiber optic sensor surface bonding on host material Shiuh-Chuan HER, Chang-Yu TSAI Department of Mechanical Engineering, Yuan Ze University, 135 Yuan-Tung Road, Chung-Li.... The strain of optic fiber induced by the host material is strongly dependent on the bonding characteristics which include the protective coating, adhesive layer and the length of bonding. The strains between......

with a constant. Saturation reduces the total absorption energy, dissipated energy, and elastic strain energy of rock samples. Key words: post-peak; saturation; strength property; damage mechanism; energy Cite... of damage variables (the ratio of the dissipated energy to the constitutive energy) increased exponentially with strain. The damage constitutive models under cyclic loading have reasonable errors......
Trans. Nonferrous Met. Soc. China 22(2012) 246-254 Modeling of strain hardening and dynamic recrystallization of ZK60 magnesium alloy during hot deformation HE Yun-bin, PAN Qing-lin, CHEN Qin, ZHANG... stress behavior of ZK60 alloy at elevated temperature was investigated. The strain hardening and dynamic recrystallization of the alloy were modeled by Kocks-Meching model and Avrami equation......
Limiting drainage criterion for groundwater of mountain tunnelCHENG Pan(程盼), ZHAO Lian-heng(赵炼恒), LI Liang(李亮), ZOU Jin-feng(邹金锋), LUO Wei(罗伟) (School of Civil Engineering, Central South University... drainage criterion should be established to balance the tunnel construction and groundwater. To assess the related problems, an limiting drainage standard ranging from 0.5 to 2.0 m3/(m·d) was suggested......
