Abstract

Elastic waves are frequently employed in Non-Destructive Testing and Structural Health Monitoring systems for damage detection and evaluation. Accurate and fast simulation of structural responses - due to high frequency ultrasonic excitation - is possible by the application of graphical processing units (GPUs). The research work presented in this paper is motivated by high demands for model sizes and GPU memories. The paper presents new developments related to the simulation framework for elastic wave propagation. The proposed software environment uses the modified local interaction simulation approach and graphical processing units to model ultrasonic wave propagation in structures. The method has been enhanced by the application of multi-GPU workstations. This allows for effective simulations that can be performed in complex structural components. The multi-GPU architecture and decomposition approach are accompanied by absorbing boundary conditions for the model, enabling the reduction of model size and replacing missing parts of the model by infinite space.
