The distribution of C-grade is like as B-grade area, but the material comprises a little clay that reduces the permeability of the material.
Analysis Method Generally, groundwater levels fluctuate according to the characteristics of precipitation events (i.e. amount, duration, and intensity) and various hydrogeological variables (e.g. topography, thickness of the unsaturated zone, and matrix composition of saturated and unsaturated materials).

In this process, a specially designed, non-consumable, rotating tool is slowly plunged into material to be joined and traversed along the length of the material.
The random nature of the fatigue crack growth data is today commonly regarded as an inherent feature of fatigue process in real materials.
As is seen in the Figures, there is not negligible influence of material property, BM, WM and HAZ.
