3DP_CONCRETE_BEAMS_SERIES_3

Dataset "3DP_CONCRETE_BEAMS_SERIES_3" presents the results of experimental research conducted on concrete beams subjected to three-point bending, manufactured using an additive 3D printing method. The specimens were printed with a single-layer dimensions of 10 × 20 mm and v.u. layer orientation,  using one-component mixture Sikacrete 751 3D . The geometrically similar beams had three different sizes Leff × D × t (Leff — distance between supports, D — effective depth, t — thickness):  120 × 40 × 40 mm,  240 × 80 × 40 mm and 360 × 120 × 40 mm.  During testing, the beams were gradually loaded at the top edge under crack-mouth-opening-displacement (CMOD) control.
The results for each beam are stored in three columns: (1) time [s], (2) load [N], and (3) CMOD [mm]. The first row contains the specimen number, while the second and third rows describe the measured parameters and their units. The datafile is split into three worksheets  "S3_40" , "S3_80" and "S3_120" reffering to results obtained for beams of 40, 80 and 120 mm depth, respectively.
Datasets "3DP_CONCRETE_BEAMS_SERIES_1", "3DP_CONCRETE_BEAMS_SERIES_2", and "3DP_CONCRETE_BEAMS_SERIES_3" were developed within the same research project (MINIATURA-7, 2023/07/X/ST8/01392) and include results for beams with different geometries.
