Abstract: Cracking control is very important for laser drilling of yttria-stabilized zirconia (YSZ). In this paper, a thermomechanical model is presented to investigate what will be happened in the trepan drilling of YSZ by a ...

Abstract: Laser drilling of alumina is a noncontact material processing method, which has great advantages over the traditional mechanical machining. However, the quality of laser drilling is still a challenge. In this study, a 2D ...

Abstract: The crack behaviors of yttrium-stabilized zirconia during laser drilling in air, vacuum, and water environments were investigated. Due to the high stress and low fracture toughness induced by tetragonal-monoclinic phase ...
