- This tool is for calculating vertical stress increment in soil induced by the applied uniform circular load, as shown in the figure above.
- The soil layer is assumed as homogeneous, elastic and isotropic.
- All the input parameters should be positive.
- The coordinates of point A are limited in the calculator (z<2B, r<0.5B).
- For "nan", "0" or "inf" displayed in Results, please check your input parameters.
