New Opportunities to Determine the Rate of Wear of Materials at Friction by the Indentation Data
The article is concerned with the determination of physical plasticity δH (the ratio of the plastic strain to the total strain) and yield stress σS by indentation and the application of these characteristics for analysis of the wear rate W during the ...

Indentation of ellipsoidal and cylindrical elastic shells [PDF]
Thin shells are found in nature at scales ranging from viruses to hens’ eggs; the stiffness of such shells is essential for their function. We present the results of numerical simulations and theoretical analyses for the indentation of ellipsoidal and ...

Permanent indentation characterization for low-velocity impact modelling using three-point bending test [PDF]
This paper deals with the origin of permanent indentation in composite laminates subjected to low-velocity impact. The three-point bending test is used to exhibit a non-closure of matrix crack which is assumed as a cause of permanent indentation ...

Competing indentation deformation mechanisms in glass using different strengthening methods
Chemical strengthening via ion exchange, thermal tempering, and lamination are proven techniques for strengthening of oxide glasses. For each of these techniques, the strengthening mechanism is conventionally ascribed to the linear superposition of the ...
