TY - JOUR TI - Thermo-plastic finite element analysis for metal honeycomb structure AU - Ji Zhanling AU - Li Yunhua AU - Li Yunze JN - Thermal Science PY - 2013 VL - 17 IS - 5 SP - 1285 EP - 1291 PT - Article AB - This paper deals with thermal-plastic analysis for the metal honeycomb structure. The heat transfer equation and thermal elastoplastic constitutive equation of a multilayer panel are established and studied numerically using ANSYS software. The paper elucidates that only the outer skin produces easily plastic deformation, and the outer skin still exists some residual stress and residual deformation after cooling. The dynamic evolution of plastic deformation and material performance degradation under high energy thermal load are revealed.
