Effective model for elastic waves propagating in a substrate supporting a dense array of plates/beams with flexural resonances
Jean-Jacques Marigo, Kim Pham, Agnès Maurel +1
We consider the effect of an array of plates or beams over a semi-infinite elastic ground on the propagation of elastic waves hitting the interface. The plates/beams are slender bo…
A diffuse interface model for the analysis of propagating bulges in cylindrical balloons
Claire Lestringant, Basile Audoly
With the aim to characterize the formation and propagation of bulges in cylindrical rubber balloons, we carry out an expansion of the non-linear axisymmetric membrane model assumin…
Buckling of an elastic ridge: competition between wrinkles and creases
Claire Lestringant, Corrado Maurini, Arnaud Lazarus +1
We investigate the elastic buckling of a triangular prism made of a soft elastomer. A face of the prism is bonded to a stiff slab that imposes an average axial compression. We obse…
Vibroacoustics of the piano soundboard: Reduced models, mobility synthesis, and acoustical radiation regime
Xavier Boutillon, Kerem Ege
In string musical instruments, the sound is radiated by the soundboard, subject to the strings excitation. This vibration of this rather complex structure is described here with mo…
Vibrational and acoustical characteristics of the piano soundboard
Kerem Ege, Xavier Boutillon
The vibrations of the soundboard of an upright piano in playing condition are investigated. It is first shown that the linear part of the response is at least 50 dB above its nonli…
Vibroacoustics of the piano soundboard: (Non)linearity and modal properties in the low and mid-frequency ranges
Kerem Ege, Xavier Boutillon, Marc Rébillat
The piano soundboard transforms the string vibration into sound and therefore, its vibrations are of primary importance for the sound characteristics of the instrument. An original…
Synthetic description of the piano soundboard mechanical mobility
Kerem Ege, Xavier Boutillon
An expression of the piano soundboard mechanical mobility (in the direction normal to the soundboard) depending on a small number of parameters and valid up to several kHz is given…
Global and local synthetic descriptions of the piano soundboard
Kerem Ege, Xavier Boutillon
Up to around 1.1 kHz, the soundboard of the piano behaves like a homogeneous plate whereas upper in frequency, it can be described as a set of waveguides defined by the ribs. In co…
Estimations of non-linearities in structural vibrations of string musical instruments
Kerem Ege, Marc Rébillat, Xavier Boutillon
Under the excitation of strings, the wooden structure of string instruments is generally assumed to undergo linear vibrations. As an alternative to the direct measurement of the di…
Comparison of the vibroacoustical characteristics of different pianos
Xavier Boutillon, Kerem Ege, Stephen Paulello
On the basis of a recently proposed vibro-acoustical model of the piano soundboard (X. Boutillon and K. Ege, Vibroacoustics of the piano soundboard: reduced models, mobility synthe…
End conditions of piano strings
Kerem Ege, Antoine Chaigne
The end conditions of piano strings can be approximated by the input admittance at the bridge. Proper measurements of this value are therefore required. A method of validation of a…
Macroelement modeling of shallow foundations
Charisis Chatzigogos, Alain Pecker, J. Salençon
The paper presents a new macroelement model for shallow foundations. The model is defined through a non-linear constitutive law written in terms of some generalized force and displ…
