From: Nonlinear mechanical response of finite-length soft composites with random dislocations
The imperfect models- i.e., models with dislocations- of the HLM model (for modeling the RNA strand) and the FBM, 1DSM, and 2DSM (for modeling the DNA strand) are presented in panels (a), (b), (c), and (d), respectively. \(j_{0}\), \(j_{n}\) (\(n=1,2\)), and \(j_{n^{\prime }}\) (\(n^{\prime }=3,4\)) represent the stiffnesses of the linear springs mimicking the molecular bonds between the subsites of the building blocks. The masses of the sub-sites inside the BLUCs of the models are labeled from \(M_{1}\) to \(M_{N_{s}}\).
