Effect of stress and temperature on the micromechanics of creep in highly irradiated bone and dentin

► First systematic study of varying creep stresses on bone and dentin at nanoscale. ► HAP in highly irradiated bone and dentin sheds load during creep at all stresses. ► This suggests HAP-collagen interfacial damage due to irradiation and applied stress. ► HAP and fibril strain rates increase with stress, temperature and irradiation. ► Temporal evolution of strains different in bone and dentin
