Mm. Elhawary et al., A NONLINEAR FINITE-ELEMENT ANALYSIS OF HORIZONTAL ELASTOMERICS OF REVOLUTION, Finite elements in analysis and design, 21(3), 1996, pp. 145-157
A nonlinear composite finite element analysis of layered elastomeric,
initially flat, solids of revolution is presented. The analysis has mu
ch lower computational cost compared to discrete or three-dimensional
composite analyses. The nonlinearities of the presented theory include
large displacements of stiff layers and large displacements and defor
mations of flexible layers along with the nonlinear material behavior
of flexible layers. The finite element technique is; based on the mini
mum potential energy concept and the Newton-Raphson method is used to
solve the resulting nonlinear equation. After the verification of the
thoery, a parameter study involving the ratio between the thickness of
stiff and flexible layers is presented.
