| Περιγραφή: | This work introduces a dynamic model for a tensegrity-shell structure using the multi-particle position method. The approach begins by removing rigid body motions to determine the deformation field of the structure and derives stresses in the axial elements through the endpoints positions (particles). The shell element strains are derived through the deformation gradient obtained by minimizing the relative displacement errors of particles. The projection of this value onto the direction of the particle of interest and its adjacent defines the particle strain, leading to stress derivation using the linear elastic model. This simplifies the elastic strain potential energy and, with kinetic energy, forms the Lagrangian equation. Unlike conventional finite element methods for shell elements, which rely on displacement variables, shape functions, and intricate strain computations, this approach establishes a straightforward relationship between the strains and particle positions, thus simplifying the expression for elastic potential energy for the formulation of the dynamic equation. Validation with commercial software and case studies confirms its accuracy and efficiency, showing its potential as a robust alternative for coupled discrete-continuum model dynamic analysis. |
