Advanced Engineering Materials, EarlyView.A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

MODULUS OF ELASTICITY AND MODULUS OF RUPTURE OF ELECTRICAL PORCELAIN
Journal of the Ceramic Association, Japan, 1937 Measuring the modulus of elasticity and that of rupture for electrical porcelain with the small cross sectional area, the following results have been obtained.1. When the grain size of green body is reduced, the modules of rupture and the modulus of elasticity become larger, but the increase of the latter is smaller when compared with that of the ...

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

Advanced Engineering Materials, EarlyView.A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...
