Uniaxial tensile test data for VHB tape and Elastosil 4:3 at different loading rates

This dataset contains the experimental raw data from the uniaxial mechanical testing of soft elastomers: force-displacement curves and displacement fields for all experimental repetitions. Every specimen (a rectangular plate with a circular hole) is tested under uniaxial tensile loading until rupture.Elastosil samples had a thickness of 2 mm, and VHB samples had a thickness of 0.5 mm. The initial length between grips was set to 15 mm. The files for the force-displacement data (zip file: force_displacement_curves) and the DIC displacement fields are named according to:- the type of sample (elastosil_43 or vhb),- the deformation rate (displacement rate of the clamps) (e.g., ldot = 15 mm/s),- the diameter of the hole (plate_d5mm),- and the number of the experiment up to the total number of repetitions under the same test conditions (rep1, rep2, and rep3). Inside each .zip file, all horizontal (prefix u1_<img>) and vertical (prefix u2_<img>) displacement fields are provided for each loading stage, where <img> indicates the image number. Information on the acquisition rate of images is provided within each folder (README.md), allowing each displacement field to be related to a specific value of the clamp displacement during loading.
