Laser hole cutting into bronze: thermal stress analysis
journal contribution
posted on 2023-06-10, 07:03 authored by B S Yilbas, S S Ahktar, Chris ChatwinChris ChatwinLaser hole cutting in bronze is carried out and the thermal stress formed in the cutting section is examined using a finite element code. The cut geometry and microstructural changes in the cutting section are examined using optical microscope, scanning electron microscope (SEM), and energy dispersive spectroscopy (EDS). It is found that the high conductivity of bronze increases the cooling rates within the cutting section, which influences the thermal stress field in the cutting region. The residual stress predicted is in the order of 200 MPa within the vicinity of the hole circumference. The striation pattern at the kerf surface changes towards the hole exit, which is associated with the drag forces developed in this region. © 2011 Elsevier Ltd. All rights reserved.
