Crystal plasticity simulation of the effect of grain size on the fatigue behavior of polycrystalline Inconel 718

, 2018
A microstructure-based model that accounts for the effect of grain size has been developed to study the effect of grain size on the fatigue life of Inconel 718 alloys.

A time-discontinuous elasto-plasticity formalism to simulate instantaneous plastic flow bursts [PDF]

arXiv
Plastic flow is conventionally treated as continuous in finite element (FE) codes, whether in isotropic, anisotropic plasticity, or crystal plasticity. This approach, derived from continuum mechanics, contradicts the intermittent nature of plasticity at the elementary scale.

Non-Schmid Effects In Perfect Single Crystal Metals At Zero Temperature [PDF]

arXiv, 2017
A long standing postulate in crystal plasticity of metals is that yielding commences once the resolved shear stress on a slip plane reaches a critical value. This assumption, known as Schmid law, implies that the onset of plasticity is independent of the normal stress acting on the slip plane.

Development of a Novel, All‐Aromatic High Tensile Modulus Liquid Crystalline Polyimide for Fused Filament Fabrication Applications

Advanced Functional Materials, EarlyView.
A novel, high tensile modulus, fully aromatic thermotropic liquid crystalline polyimide (LCPI) with better solvent resistance and thermal stability is synthesized. Tensile specimens are fabricated using both injection molding and FFF processes, accomplished via lower viscosity enabled by the LC phase.

Comparison of Lithium Gadolinium Borate Crystal Shards in Scintillating and Nonscintillating Plastic Matrices [PDF]

arXiv, 2011
We present a method for detecting neutrons using scintillating lithium gadolinium borate crystal shards in a plastic matrix while maintaining high gamma rejection. We have procured two cylindrical detectors, 5"\times5", containing 1% crystal by mass. Crystal shards have a typical dimension of 1 mm.
