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...
H 24 AlRbO 20 S 2 has the largest shear modulus and Young's modulus, so it has the highest hardness. In addition, by calculating the anisotropy index of the hydrides, it is proved that they are anisotropic. H 24 AlKO 20 S 2 has the strongest anisotropy and the value of A U is ...
With a tensile strength over 100 GPa, and a Young's modulus over 1 TPa, carbon nanotubes (CNTs) are considered as one of the strongest materials ever found and exhibit overwhelming advantages for storing mechanical energy. For example, the tensile‐strain energy density of CNTs is as high as...

High-capacity optical long data memory based on enhanced Young’s modulus in nanoplasmonic hybrid glass composites Storing and reading data for long periods of time is of huge interest. Here, the authors demonstrate long optical data memory with nanoplasmonic hybrid glass composites. They show conti...
Being 100 times stronger and five times stiffer than steel at a fraction of its weight, SWCNTs are known for their unparalleled mechanical toughness. They combine a high Young’s modulus of 1 TPa with a tensile strength exceeding 100 GPa and an elastic strain limit of up to 20–30% ...
The three hydrides were found to exhibit a wide band gap of [4.35, 4.48, 3.77] eV for SrAlH5, BeAlH5, and CaAlH5 respectively. Phonon calculations validated the stability of the studied systems. Mechanical properties, including bulk modulus, shear modulus, Young's modulus, and Poisson's ...
Poisson's ratio and Young's modulus) and the acoustic logging parameters or rock physical parameters (e.g. porosity) could not be established based on the rock mechanical experiment results of many cores. Therefore, the same geological horizon in the 3D geomechanical model is assigned with the ...
