Capacity of a condenser whose plates are circular arcs

Capacity of a condenser whose plates are circular arcs

We find an asymptotic formula for the conformal capacity of a plane condenser both plate of which are concentric circular arcs as the distance between them vanishes. This result generalizes the formula for the capacity of parallel linear plate condenser found by Simonenko and Chekulaeva in 1972 and sheds light on the problem of finding an asymptotic formula for the capacity of condenser whose p...

Load Carrying Capacity of Simply Supported Variable Thickness Circular Plates

The calculation of the load carrying capacity of variable thickness circular plates subjected to arbitrary rotational symmetric loading is presented. The analysis considers plate materials that obey either the square or the Tresca yield criterion. By using upper and lower bound theorems of limit analysis, corresponding estimations for the load carrying capacity of the plate are obtained. It is ...

Triangulations with Circular Arcs

An important objective in the choice of a triangulation is that the smallest angle becomes as large as possible. In the straight line case, it is known that the Delaunay triangulation is optimal in this respect. We propose and study the concept of a circular arc triangulation— a simple and effective alternative that offers flexibility for additionally enlarging small angles—and discuss its appl...

Nerve Complexes of Circular Arcs

We show that the nerve complex of n arcs in the circle is homotopy equivalent to either a point, an odd-dimensional sphere, or a wedge sum of spheres of the same even dimension. Moreover this homotopy type can be computed in time O(n log n). For the particular case of the nerve complex of evenly-spaced arcs of the same length, we determine the dihedral group action on homology, and we relate th...
