WitrynaWhen a nano indentation test is carried out on a crystalline solid with a low dislocation density so that the indenter tip loads on to a dislocation-free area, then, because the …

Witrynain contact with it. At this point the loading phase begins (Fig. 1). The sample is being pressed by the indentation probe while load (𝑃) and surface displacement (or indentation, ℎ) are recorded. Commercial nano-indenters can be operated either in load- (i.e. controlling the force applied to the sample) or indentation-control Witryna(76,8 MPa) than that from 4-point bending test (73 MPa). A linear regression for converting MOR from 3-point to 4-point bending test was proposed for these Eucalyptus specimens: MOR 4p = 0,889 × MOR 3p + 5,14 in MPa (R²=0,74). The correlation of MOR in 3-point bending with density was higher (R²=0,57) than in 4 …
