Calculation of gravity effects of tridimensional structures by analytical integration of a polyhedric approximation and application to the inverse problem
Main Article Content
Abstract
Analytical expressions, rapid in computer time, are derived to calculate the gravity anomaly on an external point due to a model of homogeneous tridimensional body defmed by providing several parallel vertical polygonal contour sections laterally assembled by triangular faces. Such type of body is then used for modeling solutions of the inverse gravity problem and some suggestions on convergence are made. Examples of direct and inverse calculations are also presented.
