GFRP V-structure blast simulation results

This is the data from the thesis titled:

Response of composite and steel V-structures to localised air blast loading (2023)

This compressed folder contains the raw data extracted from the GFRP V-structure blast simulations. The files have first been separated based on the V-angle and fibre orientation. In each of the subfolders, the V-tip radii and charge mass configurations were varied. Included in the files are the CSV files of the mid-point displacement time histories, projected delaminated area of each layer, and ridge node z displacements and x coordinates. Also included are the fluid-structure interaction forces which can be used to extract the impulse transferred from the explosive loading to the target structure. All simulations were performed on LS-DYNA R8.

The first zipped folder titled - GFRP_V_structure_blast_results.zip contains four subfolders labelled:

105_00_90

105_45_45

120_00_90

120_45_45

- The first number represents the V-angle, while the second set of numbers indicate the fibre orientation, either 0 deg/90 deg or +45 deg/-45 deg.

- The subfolders inside each of these folders contain a series of csv files with the displacement and coordinate histories for the blast simulated GFRP V-structures. These can be used to generate displacement histories in the ridge plane.

- Included are also csv files of the average fluid-structure interaction forces which can be used to obtain the impulse transferred from the explosive to the V-structures.

- A series of png images for each contact layer between the shell elements are also provided in each folder showing the delamination at the end of the simulation in that contact layer. These can be used to determine the total projected delaminated area.
