When two bodies are in contact, various surface/subsurface damage problems may arise,
which significantly shorten the service lives of functional components. These damage …

In typical metallic contacts, stresses are very high and result in yielding of the material.
Therefore, the study of contacts which include simultaneous elastic and plastic deformation …

A transient thermomechanical sliding model for the contact between elastic-plastic asperities
is established to analyze the contact behaviors of micro asperity in the sliding process …

In a standard design practice, it is often necessary to assemble engineered structures from
individually manufactured parts. Ideally, the assembled system should perform as if the …

Wear is one of the most fundamental topics in tribology and adhesive wear is argued as the
least avoidable wear type. Numerical techniques have allowed advances in more realistic …

The experimental study of joint mechanics has been limited in its effectiveness due to the
high uncertainty associated with assemblies of sub-components. In particular, two …

The wear condition of the piston/cylinder pair is crucial to the performance and reliability of
the axial piston pump. The hard piston surface, the soft cylinder bore surface, and the …

This paper presents an analysis of the transient contact solutions of wheel-rail frictional
rolling impacts calculated by an explicit finite element model of the wheel-insulated rail joint …

A finite element (FE) model is presented for the evolution of fracture and friction in elastic-
plastic adhesive spherical contact. The model is based on a realistic criterion of ductile …

Macroscopic wear experiments in mid 1950s suggested an empirical wear relation: wear
volume is linearly proportional to load and sliding distance. Recent asperity-level wear …
