Data for "A nanoindentation study of attenuation in geological materials" - quartz, halite, olivine and PMMA

Dataset for forced oscillations experiments with the nanoindenter for halite, pmma, olivine and quartz. The files are *.pkl format (pickle) and can be accessed with the "pickle" library in python. The name of each file contains: the name of the tested material, the oscillation period in seconds, the test number (multiple tests for each period). The oscillation amplitude is 10% of the test's load "P", unless stated otherwise - for example: A20 means that the amplitude is 20% of the load in that test. Each file contains the following columns: experiment time (in seconds), load (in mN), displacement of the indenter tip (in nm) and may or may not contain the indentation hardness H (in GPa) from the continuous stiffness measurement method - wich is not required for the calculation of attenuation. For any questions please contact Nir Badt.本数据集用于岩盐、聚甲基丙烯酸甲酯（PMMA）、橄榄石及石英的纳米压痕仪（nanoindenter）受迫振动实验。文件格式为*.pkl（Pickle序列化文件），可通过Python的pickle库读取。每个文件名包含以下信息：被测材料名称、振动周期（单位：秒）、测试编号（同一振动周期可开展多次测试）。除非另有说明，振动幅值为本次测试载荷P的10%；例如标识A20即代表该次测试的幅值为载荷的20%。每个文件包含以下列数据：实验时长（单位：秒）、载荷（单位：毫牛mN）、压头尖端位移（单位：纳米nm）；部分文件还包含通过连续刚度测量法（continuous stiffness measurement method）得到的压痕硬度H（单位：吉帕GPa），该参数并非振动衰减（attenuation）计算的必需项。如有任何疑问，请联系Nir Badt。
