Stresses within the soil caused by a point load (Boussinesq Solution) Abaqus

This example been chosen from Example 3.4 Sam Helwany book

In this question, we intend to simulate the stresses within the soil due to the point load, in the Abaqus software

In this example , a vertical point load of 10 Kilo Newton is to be applied to the top surface of the soil and we are going to calculate the increase of stress having been caused within the soil and compare the results gained from the Abaqus software with the Boussinesq solution

The geometric shape of the soil is actually a Cylinder. The radius of the cylinder is 1 m and it is 2 meters high , 1 meter and 2 meters

The soil is assumed to be linear elastic with Young’s modulus 1e7 KPa and Poisson’s ratio 0.3
