How is the tangential slip distance calculated in the archard wear model? Was it extracted from the contact model? Hope to get a detailed answer, thank you

    Hi,

    You can see the Archard Wear code here:

    https://community.altair.com/community?id=altair_file_exchange_article_view&sysparm_article=KB0122123 

    // Get normal force
    
double normalForce = contactResults.normalForce.length();

    
// Calculate tangential displacement
    
double tangDisp = relVel_t.length() * timeStepData.timeStep;

    
// Calculate wear volume
    
double wearVol = wearConstant * normalForce * tangDisp;

    The normalForce is passed to the Archard model from the base physics model chosen. The tangential displacement is calculated per time-step based just on the relative tangential velocity of the two elements in contact.


    Regards

    Stephen
