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:
// 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.
