โœฆ Synopsis


The outstanding problem of finding a simple Muskhelishvili-type integral equation for stress problems on multiply connected domains is solved. Complex potentials are represented in a way which allows for the incorporation of cracks and inclusions. Several numerical examples demonstrate the generality and extreme stability of the approach. The stress field is resolved with a relative error of less than 10 -10 on a large, yet simply reproducible, setup with a loaded square plate containing 4096 holes and cracks. Comparison with previous results in the literature indicates that general-purpose finite-element software may perform better than many specialpurpose codes.

We present a collocation approach to the numerical solution of the Helmholtz eigenvalue problem on multiply connected domains of arbitrary shape in two dimensions. A suitable representation of the Helmholtz equation on an uniform grid is obtained and the problem is converted to the calculation of th

The no-normal-flow condition states that the stream-function is constant at solid boundaries. For multiply connected domains these (unknown) constants differ per boundary and must be determined from integral conditions. This complicates discretization and solution of the problem considerably. In thi
