Pressure measurements from internal/confined blast loading using C-4 charges

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. A journal article presenting the results has been published in the journal "Shock Waves", and the article PDF has been added to the dataset. The article DOI link is https://doi.org/10.1007/s00193-024-01161-w and the article is open access.本数据集包含由刚性钢圆筒提供的密闭空间内球形C-4炸药爆轰产生的压力记录（原始数据），所用压力传感器为Kulite HKS-375 (M)型压力传感器。实验所用刚性钢圆筒具备两种内径规格：400 mm与200 mm。针对400 mm内径钢圆筒，开展了一组测试，采用的装药重量包括50 g、65 g、75 g、100 g、150 g、200 g、300 g、400 g、500 g的C-4炸药，每组装药均重复两次测试。针对200 mm内径钢圆筒则开展了两组测试：第一组为4次完全相同的测试，均使用20 g的C-4炸药，用于验证测试重复性；第二组的装药重量分别为10 g、16 g、20 g及25 g，每组同样重复两次测试，该组额外配备了外置压力传感器与用于阴影成像的高速摄影机。所有列出的装药重量均未包含雷管，雷管会为总装药增加约2 g的等效重量。本数据集先按钢圆筒内径分类，再针对200 mm内径圆筒的测试系列进行二次划分。每个文件夹中均包含一份PDF文件，其中附有实验装置示意图以及压力传感器相对于装药的安装位置说明。本数据集附带一篇已发表于《冲击波》（Shock Waves）期刊的研究成果论文PDF，该论文为开放获取文章，其DOI链接为https://doi.org/10.1007/s00193-024-01161-w。
