SUMMARY

The Boussinesq problem of elasticity, specifically regarding a point load on an isotropic elastic infinite half-plane, has been discussed with references to the Boussinesq-Cerruti solution. Key resources include the Wikipedia page on linear elasticity and the book by Landau & Lifgarbagez, which provides a derivation of the solution. The discussion emphasizes the importance of understanding Green's tensor in this context, particularly how it behaves at infinity and the conditions of the stress tensor at the surface.

PREREQUISITES
  • Understanding of linear elasticity principles
  • Familiarity with Green's functions and tensors
  • Knowledge of Cartesian coordinate systems in elasticity
  • Basic grasp of stress tensor concepts
NEXT STEPS
  • Study the Boussinesq-Cerruti solution in detail
  • Read Landau & Lifgarbagez for comprehensive derivations
  • Explore applications of Green's tensors in elasticity
  • Investigate advanced topics in isotropic material behavior
USEFUL FOR

Researchers, graduate students, and professionals in the fields of civil engineering, mechanical engineering, and applied mathematics who are focused on elasticity theory and its applications in material science.

Where can I find the derivation of the Boussinesq problem of elasticity (point load on an isotropic elastic infinite half-plane)? Besides the original 19th century paper, of course. Thanks!

Go to:

2/3rds of the way down you find,

Boussinesq-Cerruti solution - point force at the origin of an infinite isotropic half-space,

click on "show" to get,

"Boussinesq-Cerruti solution - point force at the origin of an infinite isotropic half-space

Another useful solution is that of a point force acting on the surface of an infinite half-space. It was derived by Boussinesq[4] and a derivation is given in Landau & Lifgarbagez.[3]:§8 In this case, the solution is again written as a Green's tensor which goes to zero at infinity, and the component of the stress tensor normal to the surface vanishes. This solution may be written in Cartesian coordinates as: ..."
