Finite element analysis of erosive wear for offshore structure
Erosive wear,which is a complex material damage process caused by particle impacting on the surface of equipments,has been a major concern in oil & gas industry.In this work,we employ three-dimensional finite element (FE) method to investigate the erosion process under multiple particle impacts with both spherical and irregular non-spherical particles.We take into account both elastic-plastic material behaviors,which is described by Johnson-Cook visco-plastic model,and material removal,which is governed by the Johnson-Cook failure model.The relationships between the erosion rate and the particle velocity and impact angle are obtained and compared with published data.The implications of the current simulation results are also discussed.
