Minor differences are observed in their flow front profile.
Crack front profile of macrocrack in LM is rougher than that of BM during the stable propagation region.
We observed a notable decrease in wave dispersion as the sharpness of the wetting front profile decreased.
The analysis predicts that the single overload also affects the crack front profile, where a tunneling crack propagates with a flatter crack front in the overload affected zone.
The effects of gravitation and surface tension on the development of flow front profile and velocity field are examined for a wide range of the governing parameters (namely, the capillary and Bonds numbers).
Given the sensitivity of the dispersion effect to the wetting front profile, we also evaluated whether the water content distribution can be determined through inversion of the dispersive GPR data.
The crack front profile exhibits self-affine characteristics for segment lengths less than a critical value which was typically between 80 and 200 μm, depending on the Au foil thickness.
The approach used herein can be extended to finding closed-form solutions to other integral equations possessing similar kernels for applications such as the variation of the stress intensity factor due to an arbitrary crack front profile (work in progress).
