摘要
Mechanical response and constitutive model of alumina under shock loading are discussed. Applying plate impact, stress-time curves of ceramic target were measured and dynamic mechanical behaviors were analyzed. Micro-cracks damage constitutive model was developed based on wing crack nucleation and growth, in which the damage parameter was described by the size and numbers of micro-cracks. Results of the model were compared to the experimental results and a good correlation is obtained.
