Abstract

I present an open source code Esh3D that evaluates the quasi‐static elastic displacement and stress fields perturbed by ellipsoidal inclusions, known as the Eshelby solution. The improvement over my previous work includes obtaining solutions in half‐space by numerically canceling the traction to stage a free surface. The discrete numerical domain allows nonplanar surface. I first briefly introduce the ellipsoidal inclusion problem and solution evaluation. Then, I describe the traction cancellation method in forming the half‐space solutions. Next, I emulate a planar fault with a low aspect ratio ellipsoid and compare the half‐space solution against the well‐known Okada solution for flat and topographic surfaces. Finally, I provide comparisons between the full space and half‐space solutions to illustrate the free surface effects on the displacement and stress fields.
