This contribution investigates the impact of variable amplitude loading on crack growth rates, highlighting the phenomena of retardation and acceleration in material behaviour. Variable loading conditions, characterised by differing magnitudes and sequences, can significantly influence crack growth, either slowing down or speeding up compared to constant loading. Through the study of compact tension specimens under two consecutive loading blocks at a constant load ratio (R=0.1), using a strip-yield model. The findings emphasise the importance of accurately modelling these dynamics for ensuring structural reliability and safety under variable loading conditions, offering valuable insights for materials engineering and structural integrity.
