TL;DR: In this article, the effect of low-frequency vibration excitation on modulation intensity and associated nonlinear wave interaction mechanisms was investigated experimentally in a cracked aluminum plate, and a clear link between modulations and thermo-elastic coupling was also demonstrated, providing experimental evidence for the recently proposed non-classical, nonlinear vibro-acoustic wave interaction mechanism.

An analysis of crack growth in thin-sheet metal via a cohesive zone model
Weizhou Li,Thomas Siegmund +1 more
TL;DR: In this article, a cohesive zone model (CZM) is applied to crack growth in thin sheet metal and cracks are determined from results of global measurements and micromechanical damage models, and crack propagation in constrained center-cracked panels is analyzed to verify the choice of CZM parameters.

Buckling of cracked thin-plates under tension or compression
TL;DR: In this paper, the buckling analysis of variously cracked rectangular elastic thin-plates under tension and compression is considered, and several numerical analyses, carried out by using the Finite Element Method (FEM), are performed in order to determine the critical load multiplier, both in compression and in tension, by varying some plates' parameters.

Stability of Plates Using the Finite Element Method
Kanwar K. Kapur,Billy J. Hartz +1 more
TL;DR: In this paper, the finite element method of structural analysis is extended to the problem of stability of rectangular plates for constant and variable direct stresses and shear stresses, in conjunction with the stiffness matrix, allow an easy modification of the conventional plate stiffness matrix to include the effects of in-plane stresses.

On the buckling of thin tensioned sheets with cracks and slots
G.F. Zielsdorff,R. L. Carlson +1 more
TL;DR: In this paper, the problem of local buckling in tensioned sheets with holes is discussed in relation to its effect on fracture and fatigue characteristics, and the results of an experimental investigation designed to determine the tensile buckling stress are presented.

The vibration characteristics of a tensioned plate containing a fatigue crack
TL;DR: In this article, the vibration characteristics of a simplified model of an aircraft fuselage panel, containing a fatigue crack, were obtained using the finite element displacement method, which is a preliminary to the determination of the fluctuating stresses at the tip of the crack.
