Some of the aspects involved in modelling frame-panel interaction by computer methods are discussed. These include the different types of infill and their strength and failure properties, the forces of interaction, and methods for handling material nonlinearity.
 The use of the finite element method to implement the analysis is described and examples are presented to illustrate the application of the method.

Element Method

Contact problem, which exists widely in mechanical engineering, civil engineering, manufacturing engineering, etc., is an extremely complicated nonlinear problem. It is usually solved by the finite element method. Unlike with the traditional finite element method, it is necessary to set up contact elements for the contact analysis. In the different types of contact elements, the Goodman joint elements, which cover the surface of contacted bodies with zero thickness, are widely used. However, there are some debates on the characteristics of the attached elements of the Goodman joint elements. For that this paper studies the type, matching, and meshing of the attached elements. The results from this paper would be helpful for the finite element contact analysis.

Element Method

In borehole electromagnetics, both cylindrical and planar interfaces are present, leading to nonseparable field equations. The problem is two‐dimensional (2-D), and the finite‐element method is usually employed for solution. In this paper, the Generalized Haskell Matrix/Layer Eigenstate Propagator method is introduced to this class of problems. In the method, the solution problem is decomposed into a set of one‐dimensional (1-D) problems, and then the 1-D solutions are combined to form the final solution. The method employs no approximation, other than discretization of a continuous system as in all computer methods. Induction logs are calculated for the 6FF40 tool and a number of models. Results agree well with those of the finite‐element method. An important case in induction‐log interpretation is studied; namely, a three‐layer formation traversed by a borehole, the center layer being an oil‐bearing (resistive) layer sandwiched between two conductive shoulder layers. Simulation shows that conventional correction methods ignoring borehole‐bed coupling can lead to resistivities that differ from the true resistivities by a factor of 2 or even higher.
