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_ ) and vertical (prefix u2_ ) displacement fields are provided for each loading stage, where 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.
