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.

Routine Testing of Bitumen Binders
Civil and Environmental Engineering, 2017 The quality of bituminous binders used in the construction and maintenance of road surfaces is currently assessed by empirical testing based on obtaining one value for specific boundary conditions, which were designed about 100 years ago. Basic empirical

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Viscosity-temperature relationships in the system Na2Si2O5-Na4Al2O5 [PDF]
, 1986 The viscosity-temperature relationships of five melts on the join Na2Si2O2-Na4Al2O5 (5, 10, 20, 30 and 40 mole percent Na4Al2O5) have been measured in air, at 1 atm and 1000–1350°C with a concentric cylinder viscometer.

Demo 14-04 Gas Viscosity Change with Temperature
, 2001 Gas from a tank feeds two identical burners through a T-tube. The gas in one arm of the tube is heated as shown in Figure 1. The heated gas has a greater viscosity, resulting in a smaller flame on the side with the heated gas, as can be ...

The effect of oxidation state on the viscosity of melts in the system Na2O-FeO-Fe2O3-SiO2 [PDF]
, 1987 The viscosities of two melts in the system Na2O-FeO-Fe2O3-SiO2 have been measured as a function of oxidation state. The experiments were conducted by concentric-cylinder viscometry, on melts equilibrated with gas mixtures in a vertical tube, gas-mixing ...
