title: Contact stress of bearing surfaces
body: <p>This is my first post to this forum. :)</p>
  
  <p>I am searching for information on how finite element code (abaqus /ansys) could be used to model the contact stress behaviour between 2 bearing surfaces? </p>
  
  <p>The key point is that there is an additional hard coating n both surfaces so as to reduce wear. </p>
  
  <p>How would one model this additional hard layer? </p>
  
  <p>Would this hard layer be represented by an additional layer of elements with a higher elastic modulus?</p>
  
  <p>Thanks
