oai:localhost:PNK-76432023-04-06T07:20:13Z An optimal control problem for single-spot pulsed laser welding Roland, Herzog Dmytro, Strelnikov single-spot pulsed laser welding problem quasilinear heat equation CC BY We consider an optimal control problem for a single-spot pulsed laser welding problem. The distribution of thermal energy is described by a quasilinear heat equation. Our emphasis is on materials which tend to suffer from hot cracking when welded, such as aluminum alloys. A simple precursor for the occurrence of hot cracks is the velocity of the solidification front. We therefore formulate an optimal control problem whose objective contains a term which penalizes excessive solidification velocities. The control function to be optimized is the laser power over time, subject to pointwise lower and upper bounds. 2023-04-06T07:20:13Z 2023-04-06T07:20:13Z 2023 Book https://link.springer.com/article/10.1186/s13362-023-00132-7 https://dlib.phenikaa-uni.edu.vn/handle/PNK/7643 en application/pdf Springer |
