Accelerated dispersion curve calculations for periodic vibro-acoustic structures

HIGHLIGHTS

• who: . and collaborators from the Jiaotong University, China have published the paper: Accelerated dispersion curve calculations for periodic vibro-acoustic structures, in the Journal: (JOURNAL)
• what: 3.2 3D periodic case
• how: In this work the (u p)-formulation is used in which the structural DOFs are the displacements u and the acoustic DOFs are the pressures p (Fahy and Gardonio 2007). In this work the ω(μ)-approach is applied first a set of real μ is imposed and next Eq 4 is solved towards ω. In this work instead the commonly applied truncation criterion is . . .
