titanium alloying methods were applied to ZL108 alloy for preparing specimens containing titanium. The specimens were tested on the MTS 810 material test system for studying their behavior of the plane... for improving the fracture toughness of the alloy ZL108. Key words: ZL108 alloy; electrolytic titanium alloying method; fracture toughness; significance test 1 Introduction The ZL108 alloy (ZAlSi12Cu2Mg1......
and quantized. They could be obtained from the dynamic triaxial test in door. The model was contrasted and validated with the results of the dynamic triaxial test in door. The comparison of the results of the dynamic triaxial test in door and the calculating results of the model indicates that all sorts of phenomenon appearing in the process of liquefaction of saturated sand could be more perfectly......
Responses of wind-induced internal pressure in a two-compartment building with a dominant opening and background porosity Part 2: Parameter analyses and design equationsQUAN Yong(全涌), YU Xian-feng(余... compartments decrease with increasing the amplitude of fluctuating external pressure coefficients or reference wind speed.Key words:dominant opening; internal pressure; background porosity; parameter analyses......
hyperbolic law (SI) were used to analyze the flow behavior of the Mg-6Gd-3Y-0.5Zr alloy after compression at temperatures of 300-500 ℃ and strain rates of 10-3-1 s-1 by using Geeble-1500 test machine... with the optimization of material parameter (SIO) exhibits the close precision to EI. The precipitated heat-resisting phase after compression is the reason for EI better fitting than PI and SI. Key words......
J. Cent. South Univ. (2016) 23: 3312-3321 DOI: 10.1007/s11771-016-3397-1 Model test to investigate failure mechanism and loading characteristics of shallow-bias tunnels with small clear distance LEI... of shallow-bias tunnels with small clear distance. Key words: shallow-bias; tunnels with small spacing; failure mechanism; loading characteristics; model test 1 Introduction Small clear distance tunnels have......
hard rock instability, an experimental study on the rockburst and slabbing process of granite was carried out using a true triaxial test system. The evolution of the AE signals was monitored and analyzed in terms of the AE hit rate, fractal dimension of the AE hit number, AE count rate, b-value, dominant frequency and microcrack type. The test results show that after rock slabbing occurs, the AE......
