Abstract
AbstractThis paper investigates the uncertainty of a hyper‐elastic model by random material parameters as stochastic variables. For its stochastic discretization a polynomial chaos (PC) is used to expand the coefficients into deterministic and stochastic parts. Then, from experimental data in combination with artificial data for elastomers the distribution of the force‐displacement curves are known. In the numerical example the PC‐based stochastic and the deterministic parameter identification are used for generation of the distribution of Ogden's material parameters.
