Investigation of Dynamic Fracture of Elastomers - I

<p>Dynamic fracture of a Poly Urethane elastomer has been investigated. Pure shear samples made of Poly Urethane have been used for this experimental work. The samples are 200 mm long, 40 mm tall and 3 mm thick.</p> <p>The test protocol involves stretching the sample first to the required strain level and then introducing a seed crack into the specimen. The seed crack then propagates through the specimen thereby breaking it into two pieces. The two steps are recorded by two cameras - a High Resolution (HR) camera to record the initial stretching and a High Speed (HS) camera to record the fracture process.</p> <p>The data set contains the initial loading (stretching) and fracture images of the experiment. The experiments have been performed by Thomas Corre and Michel Coret.</p> <p>The compressed folder consists of folders named according to the initial stretch level. For example L17 would indicate an initial stretch ratio (\lambda_y) of 1.7.</p>
