UL FEM SIMULATION OF TRANSIENT RESPONSES OF RINGS UNDER LATERAL IMPACT LOADS

    Graphical Abstract
    • Abstract
  • Considering the large-scale deformation of rings, the transientresponses of rings under several types of lateral impact loads are simulatedwith a code which is based on a UL FEM central-difference algorithmin the present paper. In this code developed by authors, the one-orderself-adaptive idea is employed in dealing with Mesh instability and contact-impact interfaces.
