Distribution of Electrical Resistivity in Single Carbon Fiber Filaments and Its Correlation With Tensile Modulus

Advanced Engineering Materials, EarlyView.
A statistical framework is applied to quantify the distribution of electrical resistivity among individual filaments of two commercially available carbon fiber types. Correlations between filament resistivity, tensile modulus, and diameter are examined and complemented by TEM analysis to provide new insight into filament‐level variability relevant for ...

Microscopic cracks identification and nonlinear creep model of shale under creep-disturbance loading

Results in Engineering
In this study, the action of creep damage evolution law of deep shale under the influence of disturbance was considered as the research object, and using a self-developed rock disturbance creep test rig, disturbance characteristics of rock creep ...

Bridges between Damage and Fracture Mechanics [PDF]

, 2001
International audience ; The chapter provides a view on the possible connections between damage and fracture mechanics in the particular case of quasi-brittle materials for which linear approaches are realistic. The objective is to offer the possibility to pass from one theory to the other during a same calculation or to obtain, from one theory ...

Numerical integration of an advanced Gurson model for shear loading: Application to the blanking process [PDF]

, 2013
A new extension of the Gurson damage model has been proposed recently to predict ductile fracture under shear dominated loads. The aim of this work is to verify the ability of this approach to simulate, in an accurate way, the damage evolution in ...

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

Advanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...
