Dynamic Crack Propagation and Its Interaction With Micro-Cracks in an Impact Problem [PDF]

Journal of Engineering Materials and Technology, Transactions of the ASME, 2021
The dynamic fracture behavior of brittle materials that contain micro-level cracks should be examined when material subjected to impact loading. We investigated the effect of micro-cracks on the propagation of macro-cracks that initiate from notch tips ...

Micro cracks distribution and power degradation of polycrystalline solar cells wafer: Observations constructed from the analysis of 4000 samples [PDF]

Renewable Energy, 2020
In this paper, the impact of Photovoltaic (PV) micro cracks is assessed through the analysis of 4000 polycrystalline silicon solar cells. The inspection of the cracks has been carried out using an electron microscopy, which facilitate the detection of ...

Nonlinear effects of micro-cracks on long-wavelength symmetric Lamb waves

Ultrasonics, 2018
For an elastic medium containing a homogeneous distribution of micro-cracks, an effective one-dimensional stress-strain relation has been determined with finite element simulations.

Experimental and micro-mechanical analysis of the mechanical and transport properties of mortar containing heat-induced micro-cracks

Cement and Concrete Composites, 2010
International audienceThis paper focuses on the effect of micro-cracks induced by a slow heating/cooling process (also called heat-treatment) in a mortar, upon its poro-elastic properties under drained hydrostatic compression, and upon its intrinsic ...

Micro armed concrete and cracks on slabs

2017 UBT International Conference, 2017
The purpose of this work is to describe fibres properties, micro armed concrete as a composite material and the use of it as a solution to prevent the cracks on slabs. The purpose of fiber usage inside a concrete mass is to create a composite material by

Effect of a micro-crack on the kinked macro-crack

Theoretical and Applied Fracture Mechanics, 2018
Abstract The solution of an infinite plane containing an arbitrarily located micro-crack and a kinked macro-crack is presented based on the distributed dislocation technique (DDT). The stress field, the plastic zone of the macro-crack tip (PZ) and the stress intensity factors at the macro-crack tip (SIFs) are obtained.
