A two-body abrasive wear model as a contact-induced fracture process

14.10.2019 1,033 Views

A recent work by the researchers from Leibniz University Hannover presents a 3-D framework for simulation of contact-driven-fracture processes (like abrasive wear) in filled elastomers. Modeling of material removal processes, like wear, to this day [...]
