Time domain boundary elements for elastodynamic contact
Alessandra Aimi, Giulia Di Credico, Heiko Gimperlein
This article proposes a boundary element method for the dynamic contact between a linearly elastic body and a rigid obstacle. The Signorini contact problem is formulated as a varia…
Higher-order time domain boundary elements for elastodynamics -- graded meshes and hp versions
Alessandra Aimi, Giulia Di Credico, Heiko Gimperlein +1
The solution to the elastodynamic equation in the exterior of a polyhedral domain or a screen exhibits singular behavior from the corners and edges. The detailed expansion of the s…
Fast Barrier Option Pricing by the COS BEM Method in Heston Model
A. Aimi, C. Guardasoni, L. Ortiz-Gracia +1
In this work, the Fourier-cosine series (COS) method has been combined with the Boundary Element Method (BEM) for a fast evaluation of barrier option prices. After a description of…
