高 分 子 作 業 潛變測試(Creep test) 應力鬆弛測試(Stress-relaxation test) 疲勞測試(Fatigue test)潛變性能 簡介 材料在常溫下,受到彈性限度以下之應力長時間作用時,其間並不發生變化。但在高溫環境下,受到較彈性限度低之應力作用時,材料會隨著時間漸漸地發生變形。此種在一定應力作用下,變形隨時間徐徐進行之...
What is the creep behaviour of these high strength magnesium alloys? Planar flow cast magnesium alloys have been cast and extruded. The mechanical properties in tension and compression, the stress-relaxation in compression and the tensile creep properties have been tested at temperatures from RT to ...

The analysis showed that differential swelling stresses and thermal stresses undergo ...
A quantitative analysis of the stress dependence on stress relaxation creep rate during hold time under creep-fatigue interaction conditions has been conducted for 1Cr-Mo-V steel. It was shown that the transient behavior of the Norton power law relation is observed in the early stage of stress ...
Using a visco-plastic law derived from in-situ experiments, the experimentally measured and calculated stresses during cooling show a good agreement when creep predominates. However, when stress relaxation dominates accounting for the decrease in dislocation density during cooling is essential....
In the process of the continuous straightening during continuous casting, elevated temperature creep and stress relaxation are remarkable. During continuous straightening, temperature of steel billet is very high, where the characteristic of deformation is low strain and low strain rate. It is a special...
Several soft tissues are inelastic and display a viscoelastic behavior (relaxation and/or creep), which is related to the shear interaction between the collagen fibers and the glycoproteins in the matrix (the matrix provides a viscous lubrication between collagen fibrils), see Minns et al. (1973)...
