Composites blast model

Engineers at the University of Sheffield have developed a robust and efficient computational model to calculate the behaviour of glass-fibre-reinforced laminate (GLARE) panels subjected to blast loadings. GLARE is commonly used in aerospace and automotive applications and the new model will inform the design of lightweight, blast-resistant structures.

Galal Mohamed and colleagues created a numerical model to study GLARE panels subjected to a blast-type pressure pulse and compared the results with experimental data on back-face deflection and post-damage observations. They found excellent agreement between the model and the test results.

The researchers undertook a further parametric study and identified GLARE as a potential blast attenuating structure, exhibiting superior blast potential to aluminium plates. They concluded that further work would study the influence of geometry in, for example, cylindrical structures, pre-pressurisation effects and boundary conditions.
