Effects of electric/magnetic impact on the transient fracture of interface crack in piezoelectric-piezomagnetic sandwich structure: anti-plane case

SVR Prediction Algorithm for Crack Propagation of Aviation Aluminum Alloy

“…Besides, Alshamma and Jassim [7] confirmed all parameters of the Paris Law in the experiment and found the crack growth speed through the experiment and analysis. On the basis of the previous studies, the investigation on crack growth and fracture is in the ascendant in recent years [8][9][10][11][12], and the main progress is described as follows: Lei [13] takes 2024-T4 aluminum alloy as the investigation object and uses the finite element method to investigate the influence rule and mechanism of overload condition on the change trend of subsequent fatigue crack growth rate (da/ dN). For the problem of crack propagation in a plate with a single hole central crack, Zhang and Wang [14] introduced a new Z fracture criterion which can well predict the crack propagating direction of mode I crack in carbon-fiber reinforced composite laminates and proposed new concepts of in-plane average strain, in-plane dilatational strain energy density factor, and reciprocal characteristic function.…”
