Improvement in thrust force estimation of solenoid valve considering minor hysteresis loop
AIP Advances, 2017 Solenoid valve is a very important hydraulic actuator for an automatic transmission in terms of shift quality. The same form of pressure for the clutch and the input current are required for an ideal control.

Influence of Parameter Variation in Analytical Preisach Model on Shape of Hysteresis Loop
IEEE AccessThe Analytical Preisach Model (APM) describes the magnetization characteristics of materials with high accuracy and good universality, and the corresponding mathematical equations of the model are analytical expressions, which makes it very easy to solve

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
