Abstract: Under the matrix loss function, the necessary and sufficient conditions of linear admissible estimates of nonestimatible parameter functions for a general linear model are obtained.
The flow function method is used to build the kinematically admissible velocity field, the strain rate field and the upper bound deformation power of wide section Aluminum shape extrusion.
