Query: Parameter Identification in Viscoplasticity using Transitional Markov
  Chain Monte Carlo Method   To evaluate the cyclic behavior under different loading conditions using the
kinematic and isotropic hardening theory of steel, a Chaboche viscoplastic
material model is employed. The parameters of a constitutive model are usually
identified by minimization of the difference between model response and
experimental data. However, measurement errors and differences in the specimens
lead to deviations in the determined parameters. In this article, the Choboche
model is used and a stochastic simulation technique is applied to generate
artificial data which exhibit the same stochastic behavior as experimental
data. Then the model parameters are identified by applying an estimation using
Bayes's theorem. The Transitional Markov Chain Monte Carlo method (TMCMC) is
introduced and employed to estimate the model parameters in the Bayesian
setting. The uniform distributions of the parameters representing their priors
are considered which literally means no knowledge of the parameters is
available. Identified parameters are compared with the true parameters in the
simulation, and the efficiency of the identification method is discussed. In
fact, the main purpose of this study is to observe the possibility of
identifying the model and hardening parameters of a viscoplastic model as a
very high non-linear model with only a surface displacement measurement vector
in the Bayesian setting using TMCMC and evaluate the number of measurements
needed for a very acceptable estimation of the uncertain parameters of the
model.
