【 摘 要 】

Tubes and tubeless wheels for light and medium commercial vehicles manufactured by cold forming slit hot rolled strips of low carbon steel with or without micro alloy. During the manufacture and formation of strips, the wheel rim crack becomes a major problem in the production line. This simulation discussed one type of failure on rim wheels, where the rim wheel was thinned down locally and back in the weld. The area tested for cracks was the middle part of the rim which was given a force of 2800 LBS and then converted to Newton to be 12455 N, meshing at 8 mm. The analysis results on deformation obtained a maximum value of 0.28174 MPa, at the maximum principal stress obtained a maximum value of 381.92 MPa, the maximum shear stress obtained the maximum value of 123.27 MPa, and the equivalent stress obtained a maximum value of 218.91 MPa, therefore the stress intensity factor (K) of a material with a certain geometry in elastic loading conditions from the results of crack test showed the maximum SIFS (K1) value of of 95.533 MPa. And in J-Integral, the maximum value was 0.042844 mJ/mm2.
