WebMar 4, 2024 · According to the literature, in midterm studies of the highly cross-linked polyethylenes (with mean follow-up durations of approximately 5 years) investigators typically excluded the penetration data from the early bedding-in period (i.e., when creep is substantial) to obtain a more accurate measure of the actual steady-state wear rates [ 7 ]. WebJan 19, 2024 · New concepts Molecular dynamics (MD) simulation is a major asset in polymer modeling. Nevertheless, constructing close-to-equilibrium initial structures (i.e., a key to achieve realistic polymer models) is a great challenge.Due to the lack of a standard protocol to build up close-to-equilibrium initial structures, most existing MD methods can …
