Application of ABAQUS software in solution of Hertz's contact problem

For the example of surface-to-surface contact,contact problem of two long cylinders is analyzed using ABAQUS software.The comparing analysis on ABAQUS finite element analysis result and Hertz's solution has been made.When used ABAQUS software to solve contact problem,in order to ensure the precision of finite element analysis result and to reduce the system resource,the contact area is estimated and fine meshed.Element grid edge length at the contact area and its adjacent area of contact bodies should be less than length of short half axis of the contact ellipse.As it less than 50% length of short half axis,ABAQUS software analysis result is accurate.
