Hello ,


To validate the bogie train , i musn't have  a very big value of constraint  more than the elastic yield of the materiel  .whereas the exceptional static was  applied , I have found a maximum stress at the level of the contact as shown in the figures  (I used a type of contact Tied). I'm waiting for your help because i dont know how to distress this area of contact

    Hi,

    Can you tell about the unit system being used? Yield stress of the material?

    Element quality in that zone and also about overall element quality?

    Loads and constraint locations?

    Hi , 

    it is because i have chosen the wrong contact surface ( i selected all the elements even the elements that arent in contact with each other )
