Martin Kristoffersen,


This dataset contains pressure recordings (raw data) from detonations of spherical C-4 charges inside a confined space provided by rigid steel cylinders with pressure sensors (Kulite HKS-375 (M) pressure sensors). Two different internal diameters were used for the rigid steel cylinders, 400 mm and 200 mm. A single test series was performed using the 400 mm cylinder, using charge sizes 50 g, 65 g, 75 g, 100 g, 150 g, 200 g, 300 g, 400 g, 500 g of C-4 with two repetitions of each. Two test series were performed on the 200 mm cylinder; 1) a series of four identical tests detonating 20 g C-4 to test repeatability, and 2) a series with charge sizes 10 g, 16 g, 20 g and 25 g with two repetitions of each, which also included additional external pressure sensors and a high-speed camera for shadowgraphy imaging. All listed charge sizes are without the detonator, which adds an equivalent of approximately 2 g to the charge. The dataset is divided by the steel cylinder diameter and then by test series (for the 200 mm cylinder). Included in each folder is a PDF with a sketch of the experimental setup and the positions of the pressure sensors with respect to the charge.


Steps to reproduce

1. Produce rigid steel cylinders with specified diameters. 2. Place pressure sensors (Kulite HKS-375 (M)) at desired locations. 3. Make C-4 charges of relevant sizes and add detonator. 4. Detonate. 5. Assess pressure recordings.
