中文摘要	The interfacial debonding of an inner-surface-coated hollow cylinder with multiple pre-existing surface cracks is presented. The cylinder is assumed to be exposed to convective heating at the inner surface while the outer surface is perfectly insulated. The failure criterion based on the adhesion strength is adopted, in which the interfacial stresses are considered to be responsible for interfacial debonding initiation. By using the finite element (FE) method, the transient temperature and induced interfacial stresses are calculated for the cylinder. Based on dimensional analysis, the sensitivity analysis of interfacial stresses is obtained as a function of various dimensionless parameters such as time, convection severity, material constants, crack depth as well as crack spacing. These results may provide some useful references for coating/substrate system design under thermal loading.
