To study the behavior of a carbon fiber reinforced plastic laminate under a bi-axial stress state, a new type of cruciform specimen has been developed. This specimen is loaded bi-axially under static and cyclic fatigue loadings. The experiments are monitored simultaneously using Digital Image Correlation with two High-speed cameras, and infrared thermography. A comparison between the measurements and finite elements model is used to validate the design of the sample.
