Abstract

A new whole field methodology is proposed for stress separation using only isochromatic data collected over the field for normal and oblique incidences. For this purpose, a non-linear least squares approach is adapted to process the data. Numerical experimental is carried out on a disc under diametral compression to show its validity.
