---Cyclic bending---

    - only specimen 0004, 0005, 0006, 0041, 0042 is included
    - each specimen has a single .xlsx file as data file which was created from the raw machine data
    - the data corresponds to the corresponding paper
    - unit of "Weg" (position) is mm
    - unit of "Kraft" (force) is kN
    - negative signs correspond to the polarity of the force sensor
        --> positive displacements lead to positive forces
    - data is acquired as one of the following:
        a) load cycle wise e.g. "TrendMonData" or "Belastung_n1.txt"
        b) as snapshot over time
           e.g. spreasheet "500 LW_n1.txt" --> the first 500 LC resolved over time in force and displacement of the hydraulic cylinder
           e.g. spreasheet "500 LW_n2.txt" --> the second 500 LC (500-1000) resolved over time in force and displacement of the hydraulic cylinder
    - some of the naming is unfortunately in german (use translator if necessary)
