EDEM中JKR模型中颗粒表面能量与颗粒粘度之间的关系？有没有什么换算公式
JKR模型的计算公式和相关参数的物理意义，可参考以下两篇文献：Baran, O., DeGennaro, A., Rame, E., & Wilkinson, A. (2009). DEM Simulation of a Schulze Ring Shear Tester. Proceedings of the 6th International Conference on Micromechanics of Granular Media, 1145, pp. 409-412.Johnson, K. L., Kendal, K., & Roberts, A. D. (1971). Surface energy and the contact of elastic solids. Proc. R. Soc. Lond. A , 324, 301-313.
