WebThey found through a sensitivity study that the static friction coefficient of NMC-622 particles had among other parameters significant influence on their simulation results. Giménez and colleagues [ 5 ] used the DEM approach to model the mechanical properties of lithium-ion cathodes with regard to nanoindentation. WebThe determination of the coefficient of restitution is of major interest in the design of balls and surfaces. Tennis courts are required to be resurfaced every five years. ... There is a significant difference (p = 0.0003) between a hardcourt tennis CoR … WebThereby the restitution coefficient is usually underestimated, if the material is assumed to be incompressible. This misestimating can be very significant (relative errors of 100% and more are possible), even, if the actual Poisson ratio is very close to 0.5.
