Discussion of “Ghaednia, H., Wang, X., Saha, S., Xu, Y., Sharma, A., & Jackson, R. L. (2017). A Review Of Elastic-Plastic Contact Mechanics. Applied Mechanics Reviews, 69(6).”

It has been five years since this review of elastic-plastic contact mechanics was published. The area still remains very active and many advancements have been made since then. This discussion summarizes these advances and points out what might be considered the most significant ones. In some cases experimental measurements have confirmed previous theoretical predictions. In most cases the models of contact mechanics have increased in complexity in order to improve predictions for real applications. As a fundamental area, contact mechanics will undoubtedly remain active as its implementation is often required for new applications of technology to succeed.
