Structural reanalysis via force method

A Meshless-based Local Reanalysis Method for Structural Analysis

This study presents a meshless-based local reanalysis (MLR) method. The purpose of this study is to extend reanalysis methods to the Kriging interpolation meshless method due to its high efficiency. In this study, two reanalysis methods: combined approximations CA) and indirect factorization updating (IFU) methods are utilized. Considering the computational cost of meshless methods, the reanaly...

Shift-Relaxation Combined Approximations Method for Structural Vibration Reanalysis of Near Defective Systems

Structural reanalysis for defective systems and the near defective systems is discussed in this paper. Specially, by a relaxation factor embedded in the Combined Approximations (CA) approach and a frequency shift, the reanalysis problem of near defective systems with close eigenvalues can be transformed into one of defective systems with repeated ones, which is equal to the average of the close...

Structural Optimization of Motion Structure using Constraint Force Design Method

1. Abstract This research develops a new structural optimization method for foldable motion structure with repeated rigid-body mechanism cell. Compared with conventional rigid-body mechanism, there are many kinematic advantages of a motion structure as it can achieve large shape transformation for real applications such as satellite solar panels, space antennas to shelters, and swimming pool co...

Suppression of Hand Postural Tremor Via Active Force Control Method

This paper presents the behavior and the effective way to suppress the human hand postural tremor using the active force control method. The main advantages of proposed method include; its simple control technique, practically applicable in real-time due to the much lesser computational burden and the extra robustness feature the method generates. The actual tremor data from a Parkinson disease...
