Experimental assessment of the representative strains in instrumented sharp indentation
نویسندگان
چکیده
Experimental assessment of the reverse algorithms that enable the extraction of plastic properties from the load–depth of penetration curves was conducted. Results show that they predict the stresses at 3.3% and 5.7% representative strains for Berkovich and 60 cone-equivalent three-sided pyramidal indenters, respectively, with good accuracy. It was shown that the uniaxial stress–strain curves could be reconstructed from the indentation data.

Computational Modeling of the Forward and Reverse Problems in Instrumented Sharp Indentation
A comprehensive computational study was undertaken to identify the extent to which elastoplastic properties of ductile materials could be determined from instrumented sharp indentation and to quantify the sensitivity of such extracted properties to variations in the measured indentation data. Large deformation finite element computations were carried out for 76 different combinations of elasto-...

متن کاملDetermination of Elastoplastic Properties by Instrumented Sharp Indentation
Instrumented indentation methods, which provide a continuous record of the variation of indentation load, P, as a function of the depth of penetration, h, into the indented specimen, have been the topics of considerable attention in recent years. Such interest can be attributed to the following possible applications of the methods. (1) Properties such as Young’s modulus, yield strength, and str...
