Effect of laser shock peening on fatigue life at stress raiser regions of a high-speed micro gas turbine shaft: A simulation based study

Author: Pretorius, JG ; Desai, DA ; Snedden, Glen C Date: Nov 2019 Fatigue failure due to stress raiser regions on critical rotating components in gas turbine engines, such as the shaft, is a crucial aspect. Methods to reduce these stresses and improve fatigue life are a source of ongoing research. Laser ... Read more
Modelling and optimization of a deformable mirror for laser beam control

Author: Loveday, Philip W ; Long, Craig S ; Forbes, A ; Land, K Date: Mar 2008 An intra-cavity adaptive mirror is required to compensate for time-dependent phase aberrations to the laser beam, such as those caused by thermal lensing. A piezoelectric unimorph design can provide a small, low-cost deformable mirror for ... Read more
