โฆ Synopsis
For small deformations of isotropic incompressible hyperelastic materials which are superimposed upon the simultaneous inflation and extension of a cylindrical tube, new closed form solutions are derived without any restrictions on the strain-energy function. These solutions are used to derive the load-deflection relation for small radial deformations of pre-compressed long bonded cylindrical rubber bush mountings. They are also used to formulate the n = 1 buckling criterion for long cylindrical tubes which are subjected to uniform external pressure.
ZUSAMMENFASSUNG
Fiir kleine Deformationen, die der gleichzeitigen Weitung und Streckung eines zylindrischen Rahmens aus isotropischem, kompressiblem und hyperelastischem Material iiberlagert sind, werden L6sungen in geschlossener Form abgeleitet, ohne einschr~inkende Bedingungen ftir die Deformationsenergiefunktion. Mit Hilfe dieser L6sungen wird die Last-Deflektions-Beziehung ftir kleine radiale Deformationen vorgespannter zylindrischer Gummibuchsen abgeleitet. Weiterhin werden die L6sungen benutzt, urn die Knickbedingung (fiir n = 1) langer, zylindrischer Rohre zu formulieren, die gleichf6rmigem ~iusserem Druck ausgesetzt sind.
