Numerical conformal map** for underground unlined tunnels with arbitrary shapes based on Symm’s method
Conformal map** technique is important in theoretical analysis and numerical computation for the fields of stress and displacement. In general, a...

Classical FEM-BEM coupling methods: nonlinearities, well-posedness, and adaptivity
We consider a (possibly) nonlinear interface problem in 2D and 3D, which is solved by use of various adaptive FEM-BEM coupling strategies, namely the...

Explicit Solution Formulas for the Acoustic Diffraction Problem with a Slit in a Hard and a Soft Screen
We consider the boundary operators for acoustic slit diffraction problems with a hard and soft screen, respectively. This model can also be applied... -
Averaging Techniques for a Posteriori Error Control in Finite Element and Boundary Element Analysis
Averaging techniques for a posteriori error control are established for differential and integral equations within a unifying setting. The...
