Optical Method to Study Material Behaviour at High Strain Rates,pkinson bar type of arrangement where the loading is measured in the bar following the specimen. A high-speed camera of the image converter type is used to acquire time-resolved images during the loading. These images are evaluated using digital speckle photography to give the in-plane strain field.

A One Step Prediction Error Approach to the Identification of Viscoplastic Material Models,nstitutive equations and one step predictions. The differences between one-step predictions and the corresponding measurements are used to design generic one-step prediction error estimators, and in particular, the maximum likelihood method is presented. The one-step predictions are computed through

Automated Identification and Calculation of the Parameters of Non-Linear Material Models,ters. These model parameters are adjusted with respect to experimental data. A numerical tool, called FitIt [.], for an automated optimisation of model parameters is described. The underlying methods are the Levenberg-Marquardt method and the simple Gradient-method. First and second order derivative

Estimation of Material Parameters at Elevated Temperatures by Inverse Modelling of a Gleeble Experiated by inverse modelling of a Gleeble compression test during continuous cooling. The direct problem is solved using the implicit finite element program NIKE2D. The material behaviour is described by a rate independent thermo-elastic-plastic model with a nonlinear isotropic hardening law. The objec
