查询词典 failure testing

Based on the theories of rheology, Non-Newtonian Fluid Mechanics, petroleum chemistry, crystallography and pipeline technology etc. and sampling Huabei crudes, experimental indexes and programmes are drew out, integrating the oil properties and parameter analysis; in terms of the macro analysis of continuum mechanics, substantial experiments are conducted with HAAKE RS600 rotational rheometer and the rheological equation as well as the viscosity-temperature equation are further developed with tested rhrogramme and viscosity-temperature curve, respectively. Beased on the researches on thixotropic mechanism and thixotropy fluid property, hysteresis loop curve, structure failure and viscosity build-up curve as well as shear stress decrement curve for one type oil are first present in this paper. According to the theoretical researches and testing results, a novel thixotropy equationwith τ=τ_∞e~ pattern, which is of hi-accuracy, few parameter and simplicity, is developed.Considering the influence of various parameters on rheological behaviour, depressant adding condition is optimized and experimental evaluation on BEM-5P is conducted, which further unrip its mechanism on the Huabei crude. A corresponding viable pipe transportion programmel is also recommended.

The results show that the mechanical properties of this PMMA depend strongly on the testing temperature. The Young's modulus and flow stress were found to decrease with increasing temperature at low strain rate. At the strain rate of 10^(-1) 1/s, strain soften was observed under all experiment temperatures. At high strain rate, with the temperature increase, the flow stress deceases remarkably while the failure strain increases, and the strain softening was also observed at the temperature above 333K.

试验结果表明：在准静态载荷下，随着温度的升高，材料的弹性模量和流动应力减小，在应变率为10^(-1) 1/s时表现出明显的应变软化行为；在高应变率(550 1/s)下，随着温度的升高，材料的流动应力逐渐减小而破坏应变增大，当温度超过333K时也有应变软化现象发生；在相同温度下，随着应变率的升高，材料的流动应力增大，但破坏应变减小。
