Results & publications
Scientific and technological outputs obtained within the RENO research line. Several results are shared with the closely connected CORA and BISHEAR projects; they are presented here when they directly support RENO objectives in biaxial testing, shear-driven non-linearity, stability, micromechanics or radiation-related applications.

Full-field observation of buckling
Digital Image Correlation makes it possible to identify the critical response and the spatial buckling mode of the biaxially loaded region, supporting the use of cruciform specimens for stability analysis.
Experimental progress
From irradiation to residual mechanical response
Specimen irradiation with high-energy heavy ions at GSI Darmstadt has been completed, followed by shear-test campaigns on irradiated and pristine CFRP coupons. Current analyses connect these experiments with microscale modelling and residual-property assessment.
