Experimental full field analysis for dynamic fracture of elastomer membranes

Résumé

Crack speed prediction in elastomer membranes under large strain (more than 150 %) remains a delicate question which necessitates coupled experimental-theoretical investigations. In order to compare experimental results with theoretical approaches but also to improve the understanding of dynamic crack propagation in soft materials, a crucial step is the measurement and analysis of kinematic and energetic fields in the material configuration during dynamic fracture. In this way, the proposed setup consists in a two-camera setup in order to perform digital image correlation during both quasi-static loading and dynamic fracture of the sample. The variety of kinematic and energetic fields that can be computed is illustrated. Finally, two studies highlighting the promises of full-field measurements in large strain fracture mechanics are presented: the computation of the dynamic J-integral and the observation of mechanical waves during high speed crack growth in elastomer membranes.
