Dataset for an Application-Oriented Model of Functional Fatigue in Pseudoplastic Shape Memory Alloy Wires
Description
Measurement data of functional fatigue tests of shape memory alloy wires (CleanMelt, SAES Getters S.p.A., 76µm) used for modelling functional fatigue behavior in cyclic operation and the stress-strain behavior the design according to which the tests were conducted is filed in "fractional factorial design.csv" 01 - cyclic tests: measurement data of continuous thermal cycling of shape memory alloy wires under constant load and spring-load 02 - stress-strain curves: measurement data of stress-strain curves of the previously cycled shape memory alloy wires naming scheme: 01 - cyclic tests: every dataset follows the scheme: [test ID]-[date]_D[initial actuator strain]_S[maximum stress]_N[logarithm of number of cycles].csv (test ID is classified into "B" for Base, "V" for Validation and "A" for Actuator) e.g. "B-07-2025-10-30_D2.5_S200_N2.csv" meaning test #7 of the "Base"-dataset conducted on October 30th 2025, the wire was cycled with 2.5% initial actautor strain, 200MPa maximum stress for 100 cycles (log(100)=2) wire samples, that were assigned with N0 were not cycled, therfore no measurement data for cyclic tests could be obtained 02 - stress-strain curves: every dataset follows the scheme: [test ID]-D[initial actuator strain]_S[maximum stress]_N[logarithm of number of cycles].csv (test ID is classified into "B" for Base, "V" for Validation and "A" for Actuator) e.g. "V-15-D3.25_S200_N1.csv" meaning stress-strain behavior of test #15 of the "Validation"-dataset, the wire was previously cycled with 3.25% initial actautor strain, 200MPa maximum stress for 10 cycles (log(10)=1) wire samples, that were assigned with N0 were not cycled prior, therefore the initial actuator strain stated in the name of the dataset is not relevant for the characteristics of the stress-strain behavior (e.g. the stress strain behavior of "B-01-D1_S200_N0.csv" and "B-05-D4_S200_N0.csv" is identical), but needs to be specified for correctly modelling the material behavior
