Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

A Study of Flow Properties of Kuwaiti Crude Oil Obtained from Different Sources [PDF]
Journal of Petroleum Science and Technology, 2017 The rheological properties of four different Kuwaiti crude oils in the presence of polyacrylamide (PAA) were investigated. PAA was varied at three different concentrations of 25, 50, and 75 ppm to study the viscoelastic properties in the untreated ...

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science
Advanced Engineering Materials, EarlyView.We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Large Amplitude Oscillatory Shear of the Prandtl Element Analysed by Fourier Transform Rheology
Applied Rheology, 2014 This work contributes to the theory of strain controlled large amplitude oscillatory shear (LAOS) as well as modelling the key properties of type III behavior of Hyun, the decreasing storage modulus and a loss modulus with considerable maximum.

Advanced Engineering Materials, EarlyView.Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Poly(ether-ketone)/Silica Nanocomposites: Storage Modulus and Hardness
High Performance PolymersAbstract Dynamic mechanical properties of the poly(ether-ketone) (PEK) based nanocomposites reinforced with 0–30 wt.% (0-20.2 vol.%) SiO2 nanoparticles (20–40 nm) were investigated at 1 Hz over the temperature range of 30–250°C for the application in printed circuit boards/electronic substrates.
