How tangential slip distance is calculated in the archard wear model

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.
