Effective Boundary Element Corrosion Analysis of Net Structure

DUAL BOUNDARY ELEMENT ANALYSIS OF CRACKED PLATES

The dual boundary element method is formulated for the analysis of linear elastic cracked plates. The dual boundary integral equations of the method are the displacement and the traction equations. When these equations are simultaneously applied along the crack boundaries, general crack problems can be solved in a single-region formulation, with both crack boundaries discretized with discontinu...

Boundary Element Analysis of a Lined Tunnel Problem

The boundary element technique is a practical problem-solving tool and useful in comparison to other currently popular alternatives. In this paper, a circular tunnel of a diameter 3.4 m is to be excavated through a clayey soil and surrounded by concrete lining of a thickness 0.2 m, so the clear internal diameter is 3.0 m. A plane strain analysis is adopted for such problem and the soil is assum...

A Boundary Element Regularization Method for the Boundary Determination in Potential Corrosion Damage

In this paper, we consider the inverse problem for the Laplace equation in two-dimensions which requires the determination of the location, size and shape of an unknown, or partially unknown, portion @ of the boundary @ of a solution domain R from additional Cauchy data on the remaining portion of the boundary 1⁄4 @ . This problem arises in the study of quantitative non-destructive evaluation o...
