复合模量（E*，complex modulus）包括储能模量（Es）和损耗模量（El，loss modulus），两者之间的关系为...
4.7.4.1 Storage modulus Generally, storage modulus (E') in DMA relates to Young’s modulus and represents how flimsy or stiff material is. It is also considered as the tendency of a material to store energy [244]. Loss modulus (E'') is regarded as the ability of a material to dissipat...
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...
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....
A high Young's modulus, a good fracture strain, and high fracture stress are among the mechanical characteristics that outperform other materials, including graphene. Metal–ion batteries have a lot of potential thanks to excellent metallic characteristics. Li, Na, and K have the lowest diffusion ...
(see the 3D and 2D views in Fig.2a-b). The coating shell was set as 2 nm thickness, representing the amorphous carbon or PANI. The Young’s modulus and Poisson’s ratio of CuS were assumed as 60 GPa and 0.15, respectively, based on a survey of metal sulfides [29,30,31,32]. ...
The electric breakdown tests were carried out with a dielectric strength tester at a ramping rate of 500 V s−1 (Shanghai Juter High Voltage Electrical & Equipment Co., Ltd., China). All the sam- ples used for breakdown strength have a thickness of around 15 μm. Electric...
2.3.1. Young Modulus An important consideration is the strengths of MXenes as measured using Young Modulus, an intrinsic property that is the ratio of tensile stress to strain. Certain MXenes emerge as promising contenders for electrodes with exceptional mechanical resilience against fatigue so it ...
It is reasonable that the most loosely packed crystal structure — B-TiO2, with a PF of 0.617 — exhibits the lowest Young's modulus of 167.86 GPa, while R-TiO2, with a PF of 0.705, achieves a Young's modulus of 316.06 GPa. The crystal structures of these polymorphs are ...
As used herein, the term “storage modulus” or “the bulk modulus,” is equivalent to a Young's modulus, i.e., elastic modulus or modulus of elasticity. The variables E and G (as well as E′, E″, G′, and G″) are used to represent modulus values. Its value is determined by...
