โœฆ Synopsis

A method to calculate the fundamental solution of an infinite three-dimensional, linear, elastic, orthotropic, homogeneous multilayered system due to a concentrated load acting in the interior of an arbitrary layer is presented. It was found that an analytical solution does not exist due to the complexity of the eigenvalue solution of the problem. In order to compute the solution a seminumerical method was developed and the resulting equations were solved using the fast Fourier transform (FFT). This paper is based on the work developed in a companion paper (Wideberg and Benitez, Elastic stress and displacement distribution in an orthotropic layer due to concentrated load) for the fundamental solution of an orthotropic three-dimensional layer. Numerical results are presented for a graphite epoxy fibre-reinforced composite plate.

We present the solutions for displacements and stresses subjected to a vertical point load in a continuously inhomogeneous transversely isotropic half-space with Young's and shear moduli varying exponentially with depth. Planes of transverse isotropy are assumed to be parallel to the horizontal surf
