Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Creep-fatigue life evaluation of Sn-3.5Ag lead-free solder at low temperatures
Mechanical Engineering Journal, 2016 This paper describes creep-fatigue lives of Sn-3.5Ag lead-free solder at low temperatures. Since solders have lower melting temperature and electronic devices are often used at low temperature environment, it is effective for improving the fatigue life ...
