Constraints-related microscopic fatigue crack propagation behaviour of polycrystalline alloys
HeliyonBased on the microscopic polycrystalline fatigue crack propagation (MPFCP) model, the MPFCP behaviours of GH4169 alloy under different micro-notch depths and lengths (constraints) were studied from aspects of MPFCP path, MPFCP rate and stress ...

FEBS Open Bio, EarlyView.Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

Analysis of initial crack path in fretting fatigue [PDF]
Fracture and Structural Integrity, 2016 The initial crack path is analysed in a fretting fatigue test with cylindrical contact, where there is a stress gradient and a multiaxial and non-proportional stress state. For this, a cylindrical pad is pressed, with a constant normal load, N, against

Fracture Characteristics of 3D-Printed Polymer Parts: Role of Manufacturing Process
Journal of Manufacturing and Materials ProcessingUsing traditional methods to fabricate geometrically complicated items was challenging, but Additive Manufacturing (AM) has made it possible. Although AM (3D printing) was first developed to produce prototypes, in recent years it has also been utilized ...

Scripta Metallurgica et Materialia, 1995 Abstract A two-dimisnsional analysis of crack propagation in anisotropic single crystal has revealed that the cleavage path depends on the shape of the γ-plot. Consequently, for a given notch plane the fracture path has been predicted to depend on the notch front orientation.

Advanced Engineering Materials, EarlyView.Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...
