Abstract

After a brief description of the experimental set-up used for the strain analysis of composite laminates with graphite fibres and thermoplastic matrix, the results obtained using a software code suitable for reading and analysing fringe patterns are presented. In particular the program uses two different approaches: the first semi-automatic with algorithms proper of fringe tracking and the second based on Fourier transform.
