Spherical Indentation tests on rail R260 steel

This data set contains photos and measurement data from spherical indentation tests on R260 rail steel.  This data set belongs to the following journal article: Bettina Suhr, William A. Skipper,  Roger Lewis, Klaus Six: DEM modelling of surface indentations caused by granular materials: application to wheel–rail sanding, Computational Particle Mechanics, 2024, https://doi.org/10.1007/s40571-024-00816-w A flat specimen made of the R260 rail steel was indented by a stainless steel (AISI 440C) ball bearing of 8.73 mm diameter.  The following normal loads were applied for indentation tests:  100 N, 500 N, 1000 N, 2000 N, 3000 N, 4000 N, 5000 N, 6000 N, 7500 N.   For each load level, two tests were conducted to check the repeatability of the measurement.  After tests, the indent was analysed using the Alicona InfiniteFocusSL 3D optical profilometer.  The Alicona captured a 3D scan covering a 3.66 mm x 3.66 mm area (vertical resolution of 500 nm).   Available data and file naming conventions For the test at 100 N load, the available files are named as follows: 11-32__100N.jpg: image coloured by the indentation depth 11-32__100N_Diameter.jpg: image of the indent with visually measured diameter of the indent 11-32__100N.txt: point cloud of the analyzed surface The repetition measurements’ files at 100N load are named: 11-32__100N_a.jpg, 11-32__100N_Diameter_a.jpg, 11-32__100N_a.txt The files belonging to test with higher applied load are named accordingly. This research was funded in whole, or in part, by the Austrian Science Fund (FWF) project  P 34273: DEM modelling of adhesion in sanded wheel-rail contacts. This work was conducted at Virtual Vehicle Research GmbH in Graz, Austria.  The authors would like to acknowledge the financial support within the COMET K2 Competence Centers  for Excellent Technologies from the Austrian Federal Ministry for Climate Action (BMK), the  Austrian Federal Ministry for Labour and Economy (BMAW), the Province of Styria (Dept.  12) and the Styrian Business Promotion Agency (SFG).

Rock indentation tests with lateral confinement on Gildehaus Bentheim sandstone

This dataset records the test results for rock indentation on Gildehaus Bentheim sandstone with a lateral confinement up to 20 MPa and is associated with the study named 'On the effect of lateral confinement on rock-cutting tool interactions' . The original test results for rock indentation with lateral confinement are in files of .csv format. Each file is named according to 'rock type-sample ID-lateral confinement'. For example, 'GBS-AD2-20MPa.csv' refers to a test on a Gildehaus Bentheim sandstone specimen with sampleID AD2 tested at 20 MPa confinement. In each data file, there are four columns of data, that are 'Confining pressure, MPa', 'Displacement of oil cylinder, mm', 'Force, kN' and 'Displacement, mm'. The sample height has also been included and cylinder/actuator for supplying oil has a diameter of 10 mm. For test where acoustic emission data is available, the test date and time has been included.Files started with 'event data' are acoustic emission data. In each file, the first to fifth column is 'Number of Event', 'Data','Time','Decimal second' and 'Local Time'.

The stored data were obtained through Abaqus simulations. The file is organized with an arborescence specifying geometric and material characteristics of each corresponding simulation: <code>angle[°]/bulk_height[mm]/indenter_distance[mm]/hardening_coefficient/elastic_limit[MPa]</code> Four geometries were used in the study, listed below in the format <code>DI_angle_indenterDistance[µm]\bulkHeight[mm]</code> ('03' standing for '0.3'). <ul> <li><code>DI_80_100_1</code></li> <li><code>DI_85_350_1</code></li> <li><code>DI_85_100_1</code></li> <li><code>DI_80_50_1</code></li> <li><code>DI_80_100_03</code></li> </ul> A typical input Abaqus file (<code>multi_indentation.inp</code>) for the first geometry is provided. The file has a material section which is easily modified to adapt them to material characteristics. Please note that "diamond" material corresponds to the indenter which also has a rigid condition attached. Therefore its material law is not actually used during simulation.

In-vivo video microscopy of the rupturing process of thin blood vessels in transparent fish during contact with a blunt indenter

To clarify the mechanism of bruise injuries caused by blunt impact, in vivo microscopy was performed. A flat ended indenter made of transparent acrylic was loaded onto the lateral side of the tail region of anesthetized fish. The process of the rupture of thin blood vessels was recorded in two specimens. This data set includes two types of files; (1) mp4 files of the in vivo microscopy; (2) pdf files to explain the mp4 files. The mp4 files are the original data of “Fujikawa, T., Yamada, Y. In vivo video microscopy of the rupturing process of thin blood vessels to clarify the mechanism of bruising caused by blunt impact: an animal study. BioMed Eng OnLine 23, 94 (2024). https://doi.org/10.1186/s12938-024-01284-2.”

Indention mark segmentation data

This dataset includes 1120 electron microscopy images containing an indentation mark and their ground-truth masks to detect the indent marks. Both images and masks are in png format and have a (W=1024, H=768) size. The dataset can be used for semantic segmentation. The images were taken from different scanning electron microscopes (SEMs) and have different degrees of brightness and contrast.  Indentation marks are used to evaluate the mechanical properties (hardness) of materials. This<a href="https://github.com/oekosheri/line_detection_around_indent_marks"> Github repository</a> uses the attached data to segment away the indentation mark and detect lines, using OpenCV, on its sides.   Acknowledgement:  The authors gratefully acknowledge the German Federal Ministry of Education and Research (BMBF) and the government of Nordrhein-Westfalen and the Hessian ministry for supporting this work/project as part of the NHR funding.
