Fatigue (IF 6.0) Pub Date : 2024-02-16 Thomas Landron, Franck Morel, Nicolas Saintier, Viet Duc Le, Daniel Bellett, Pierre Osmond, Agathe Forré
In order to expand the number of possible applications of High Pressure Die Cast (HPDC) components using the AlSi9Cu3 alloy, the automotive industry is giving greater attention to the fatigue design of components produce by this process-material combination. The process is well known for introducing a heterogeneous distribution of casting defects. This study explores the impact of the heterogeneous

Shock fatigue damage failure boundary study of BGA solder joints based on shock response spectrum Int. J. Fatigue (IF 6.0) Pub Date : 2024-02-15 Yongbin Dang, Yi Sun, Zhiwei Hao, Qiuhua Zhang, Wei Liu, Chaozhi Yang
Multiple shock damage failure of ball grid array (BGA) solder joints is one of the important reasons for reusable spacecraft mission failure. Shock fatigue damage failure boundary of BGA solder joints is proposed based on shock response spectrum (SRS), which can be used to assess the damage failure state. Weibull distribution is employed to characterize the shock fatigue life for a specified SRS. A
