Abstract: In this contribution, we present an explicit scheme based on local time stepping respecting local wave speed and local stability limit for each finite element. The work aim is to suppress the spurious oscillations in wave propagation tasks in heterogeneous bars.
Keywords: elastic wave; finite element modelling; heterogeneous media
