Vibrations and buckling of a beam on a variable winkler elastic foundation
Moshe Eisenberger,J. Clastornik +1 more
TL;DR: In this paper, two methods for solving the eigenvalue problems of vibrations and stability of a beam on a variable Winkler elastic foundation are presented and compared, and it is concluded that the use of the element foundation stiffness approach yields better convergence at lower computation costs.

Fluid-structure interaction analysis of flexible turbomachinery
TL;DR: OpenFOAM as discussed by the authors provides flow and mesh motion solvers and is coupled to an author-developed structural solver in a tightly coupled approach using a fixed-point iteration for quasi-steady simulations.

Numerical investigation of a crash test of a composite helicopter subfloor structure
TL;DR: In this article, a detailed analysis is presented of a generic module of a composite helicopter subfloor structure, subjected to crash loading, with the explicit finite element code PAM-CRASH and is compared with the results of a drop test.

Edge waves in plates with resonators: An elastic analogue of the quantum valley Hall effect
Raj Kumar Pal,Massimo Ruzzene +1 more
TL;DR: In this paper, the authors investigate elastic periodic structures characterized by topologically nontrivial bandgaps supporting backscattering suppressed edge waves, which are obtained by breaking inversion symmetry within the unit cell.
