Finite elements for the space approximation of a differential model for salts crystallization
Alessandra Aimi, Gabriella Bretti, Giulia Di Credico +3
This article investigates a space-time differential model related to the degradation of stone artifacts caused by exposure to air and atmospheric agents, which specifically lead to…
A space-time adaptive boundary element method for the wave equation
Alessandra Aimi, Giulia Di Credico, Heiko Gimperlein +1
This article initiates the study of space-time adaptive mesh refinements for time-dependent boundary element formulations of wave equations. Based on error indicators of residual t…

Space-time boundary elements for frictional contact in elastodynamics
Alessandra Aimi, Giulia Di Credico, Heiko Gimperlein
This article studies a boundary element method for dynamic frictional contact between linearly elastic bodies. We formulate these problems as a variational inequality on the bounda…
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…
