Inverse problems with the digital image correlation: approach and applications
Fracture and Structural Integrity, 2021 A viable approach to solve inverse problems in elasticity is proposed. It is based on regression algorithms to estimate materials and/or loading parameters by fitting the experimentally-evaluated displacement field to representative analytical solutions.

Strain-Dependent Solid Surface Stress and the Stiffness of Soft Contacts
Physical Review X, 2017 Surface stresses have recently emerged as a key player in the mechanics of highly compliant solids. The classic theories of contact mechanics describe adhesion with a compliant substrate as a competition between surface energies driving deformation to ...

Evaluation of the real contact area in three-body dry friction by micro-thermal analysis [PDF]
, 2009 Many tribological properties and wear mechanisms occurring on the micro-and nanoscale are strongly controlled by the so-called real contact area (Ar) which is a small fraction of the nominal or apparent contact area (Aa). The determination of Ar is often
