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.

Permittivity and modulus spectroscopic study of BaFe0.5Nb0.5O3 ceramics [PDF]
Processing and Application of Ceramics, 2013 Ba(Fe0.5Nb0.5)O3 (BFN) powder was synthesized in single perovskite phase by conventional solid state reaction route and BFN ceramic was obtained by uniaxial pressing and sintering at 1350 °C.

Linear dependency of NMR relaxation rates on shear modulus in hydrogels [PDF]
Soft Matter, 2011 It is found that the NMR relaxation rates of diffusants in peptide hydrogels have a linear dependency on the shear modulus of the hydrogels. This finding opens the door for non-invasive and forceless mechanical characterizations of materials and tissues using NMR and MRI.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Oxidation induced changes in viscoelastic properties of a thermostable epoxy matrix [PDF]
, 2013 The thermal ageing of a neat epoxy matrix has been studied at 200°C in air by three complementary analytical techniques: optical microscopy, mechanical spectrometry and nano-indentation. Thermal oxidation is restricted in a superficial layer of about 195

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
