Abstract
Laser cutting of triangle blank from aluminum foam is carried out. Thermal stress field in the cutting section is predicted using ABAQUS finite element code in line with the experimental conditions. Laser cutting experiments are carried out prior to the model study to determine the optimum cutting parameters for the quality cuts. Temperature predictions are compared with thermocouple data obtained from the experiment. Morphological and metallurgical changes in the cut section are examined using optical and scanning microscopes, energy dispersive spectroscopy, and X-ray diffraction. It is found that von Mises attains high values along the circumference of the cut edges at the onset of cooling cycle initiation. Laser cut edges are free from defects and asperities; however, locally distributed few dross attachments take place at the kerf exit.
