Experimental analysis of residual stress evolution under cyclic mechanical loading in 42CrMo4+QT (1.7225) including parametrization data

Abstract

This data set contains various results from (cyclic) tests with 42CrMo4+QT/SAE4140. The first part contains the results of cyclic 4-point bending tests on cuboid specimens. They were used to measure the residual stress. Each specimen was loaded with a certain number of load cycles, after which the test was stopped and the residual stress was measured. From this, the development of the residual stresses under the cyclic load can be determined. The second part of the data set contains data from characterization tests. Various uniaxial tests were carried out on a material sample in order to obtain information for the parameterization of numerical models for predicting the development of residual stresses from the first part of this contribution.
