contact problem


Updated by Altair Forum User
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 ,
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 )
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?
