| 520 | _aIn many applications, such as structure, soil mechanics, soil-foundation interaction, composite materials behavior, or welded materials, when the free surface is close by, the problem of two joined quarter spaces under a body force is useful to explain the behavior of the two media under load. Due to the domain's complexity, up to date, no analytical solution for determining elastic fields inside the two regions has been offered. The problem of a point load acting at the interior of one of the two joined isotropic quarter spaces is addressed in this study. In terms of Papkovich-Neuber functions, the elastic fields for the two regions are presented. Both traction-free boundary conditions and complete interface bonding were used for the solution. To overcome the complexity of the partial differential equations of boundary conditions, Green's analysis and a proposed potential Green's function of two joined quarter spaces were integrated with the integral image method. For various material combinations, stress distributions across the two regions and displacement on the free surfaces of the two-quarter spaces are shown. The continuity of stresses and displacements at the interface was preserved, but some stress disruption on the free surface was seen. The proposed harmonic functions and/or the domain's complexity may be responsible for the stress disturbance. Despite the disturbance of the stress on the free boundary, the solution leads back to all the previously well-known problems, such as Rongved, Mindlin, Boussinesq, Cerutti, and Kelven’s problem. | ||
