RESEARCH ON DYNAMIC AND STATIC STIFFNESS CHARACTERISTICS OF MESH ELASTIC PAD
Jixie qiangdu, 2020 Elastic cushion plays an important role in alleviating the dynamic interaction between train and its running foundation. The ratio of static stiffness to dynamic stiffness is the key parameter to determine the alleviation performance of elastic cushion ...

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance
Advanced Functional Materials, EarlyView.A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Development of procedures for calculating stiffness and damping properties of elastomers in engineering applications. Part 4: Testing of elastomers under a rotating load [PDF]
A test rig designed to measure stiffness and damping of elastomer cartridges under a rotating load excitation is described. The test rig employs rotating unbalance in a rotor which runs to 60,000 RPM as the excitation mechanism.
