Damping by branching
WebApr 10, 2024 · 3D dynamic branching test. In the first numerical example, the benchmark dynamic branching test in the 3D version is illustrated and verified against former research results from Borden [40] and Wu [71]. The material variabilities are considered in simulation to verify the effectiveness and efficiency of the proposed virtual modelling fracture ... WebMar 22, 2024 · De-branching small (Spatz et al. 2007) or large (Milne 1991) conifers with a single pruning increased frequency and decreased damping ratio, but repeated partial pruning of large conifers (Moore and Maguire 2005) or a single, large decurrent tree (James 2014) revealed that the effect on frequency was negligible until more than 80% of crown …
