Li, X. (author), Benedictus, R. (author), Zarouchas, D. (author)The present work aims at understanding the stochastic matrix crack evolution in CFRP cross-ply laminates under tension–tension fatigue loading. An experimental campaign was carried out on twenty-three specimens at different stress levels, while two optical techniques were used for the in-situ monitoring of the accumulation of transverse...journal article 2023

Li, X. (author), Benedictus, R. (author), Zarouchas, D. (author)The present work aims at investigating the progressive damage accumulation process of CFRP laminates in an interactive scheme, with a special focus on the early fatigue life where mainly matrix-dominant damage accumulates and stiffness degrades significantly. An in-situ damage monitoring system, containing edge observation, digital image...conference paper 2022

Li, X. (author), Benedictus, R. (author), Zarouchas, D. (author)Ply-block size and stress level effect on accumulation of transverse cracks and delamination are investigated during early fatigue life of CFRP laminates. Tension-tension fatigue tests under different stress levels were performed for two cross-ply configurations. Edge observation with digital cameras, digital image correlation and acoustic...journal article 2022

Li, X. (author), Saeedifar, M. (author), Benedictus, R. (author), Zarouchas, D. (author)This paper investigates the loading rate effect on both mechanical properties and damage accumulation process of [0°2/90°4]S carbon fiber-polymer laminates under tensile loading. In-situ edge observations, Acoustic Emission and Digital Image Correlation techniques were utilized simultaneously to monitor the state of damage in real time. Results...journal article 2021

Li, X. (author), Kupski, J.A. (author), Teixeira De Freitas, S. (author), Benedictus, R. (author), Zarouchas, D. (author)This study investigates the early fatigue damage of cross-ply carbon/epoxy laminates. The aim is to unfold the damage accumulation process, understand the interaction between different damage mechanisms, and quantify their contribution to stiffness degradation. Tension-tension fatigue tests were performed, while edge observation and DIC...journal article 2020
