Abstract
The identifiability problem that rises in mixed numerical-experimental problems
is one of the most important issues if an experiment has to be designed for the
quantification of material parameters. This paper focuses on the relation between
various aspects of an experiment and the condition number of the information
matrix used in gradient algorithms for the parameter estimation. The initial
estimate of the parameter sets permits to indicate whether or not the designed
experiment provides the required information. A comparison is made for a
tensile specimen and a bend specimen, where different types of measurements
are simulated. Various aspects influence the optimal relation
