Abstract
The influence of biomimetic laser-shock-wave processing (BLSWP) technology on crack resistance and residual fatigue life of specimens made of D16 aluminum alloy is studied. Biomimetic parameters for BLSWP are determined by analyzing the structure of cherry leaves, on the basis of which a 3D finite element model is developed. It is established that under BLSWP, the stress intensity factors in the samples decrease, which increases their residual fatigue life. Keywords: biomimetics, laser-shock-wave processing, residual stresses, stress intensity factor, crack resistance, crack rotation, D16 aluminum alloy. sakhvadze@mail.ru
