Crystal plasticity finite element modelling of surface asperity flattening during uniaxial planar compression

Conference Paper


Abstract


  • As an important parameter of surface quality, surface asperity of cold metal

    manufacturing products is an interesting topic in metal forming. In order to figure out

    the relationship between these parameters and the surface asperity flattening, a finite

    element model is employed in the commercial finite element software ABAQUS to

    simulate the surface asperity flattening of Al plate along the rolling direction during

    uniaxial planar compression. At the certain applied strains, the surface grain of the

    sample tends to rotate and stretch along the celtain axis. With an increase of reduction,

    the texture tends to strong and obvious. When the applied strains are low, the roughness

    increment in rolling direction is proportional to the applied strain. The grain size also has

    significant influence on the surface asperity. With an increase of grain size, the surface

    roughness tends to decrease slowly, and after the compression, the sample with the

    maximum grain size has the maximum surface roughness.
