我用DMA测出了储能模量，用应力应变曲线可以知道杨氏模量，这二者要对应吗？师兄说值要相近，但我二者差...
1)storage modulus储能模量 1.The height of loss peak(tanδ)_(max)and storage modulus(E′)were re- lated with friction coefficients.研究了聚苯硫醚(PPS)/聚四氟乙烯(PTFE)复合材料的摩擦因数、磨损体积、磨损后表面的微观形貌及损耗因子峰值、储能模量对摩擦因数的影响。 2.The vibration can obviously impr...
For this novel material system, the Young's modulus, which must be known for the calculation of the strain or the required magnetic force, is yet unknown. In this work, the Young's modulus was determined by tensile testing for the main parameters particle concentration and storage conditions....
For example, the hydro-mechanical properties of the rock, strength, Young's modulus, are increasingly degraded under cyclic loading and may even cause dynamic instability events in the tunnel [[184], [185], [186]]. Another critical loading condition that can occur in an underground reservoir ...
These parameters are material parameters (Young's modulus and Poisson's ratio of steel as well as adhesive) and geometry parameters (number of turns, inner and outer diameters, and aspect ratio of steel and adhesive). The model is statically, frequency-dependently, and time-dependently ...

1 and the other samples in Fig. 3. One reason is that the control system is unstable at Hold 1 to maintain a constant strain, or unequal strains on the redundant measurements. Another reason is that the first loading GM viscoelastic equilibrium modulus differs from Young's modulus It is ...
