Dimensionless approach for transient behaviour of flexible body with time-varying length
Nihon Kikai Gakkai ronbunshu, 2023 In this study, transient analysis of flexible body motion with time-varying length is conducted using dimensionless finite element model (FEM). First, the equation of motion for a flexible body with large deformation, displacement and time-varying length

GAMM-Mitteilungen, Volume 46, Issue 1, March 2023., 2023 Abstract Compared to conventional robots, flexible manipulators offer many advantages, such as faster end‐effector velocities and less energy consumption. However, their flexible structure can lead to undesired oscillations. Therefore, the applied control strategy should account for these elasticities. A feedforward controller based on an inverse model

Review of Locking Alleviation Methods for Continuum-based ANCF Elements [PDF]
, 2022 Abstract The absolute nodal coordinate formulation (ANCF) is a nonlinear finite element approach proposed for the large deformation dynamics analysis of beam- and plate/shell-type structures. In the ANCF approach, elastic forces can be defined using three-dimensional elasticity based continuum mechanics.
