Impact analysis and performance optimisation of shock-resistant transparent structures (LIUDU19SF)
Transparent materials are essential because the human perception is principally conceived through the vision sense. Advanced transparent materials have gradually replaced their traditional counterparts, for example, glass, in many technological applications where conventional materials are infeasible and unsuitable, especially in the subjects of protective armors, optical lenses and laser equipment.
In this proposal, a novel material for the application to transparent armors will be developed to enhance the performance of complex systems with high transparency and impact resistance. The aims of this research will include five aspects:
1. Developing a model of a projectile-eroding-fragmenting layer and identifying the optimal geometric parameters of structural layers in the simulations;
2. Including energy absorbing and crack-arresting considerations into the multi-objective optimization formulation;
3. Based on Step 1 and 2, further modelling a fragmented armor debris containment layer (spall shield) to represent the impact process so that the client’s needs can be met;
4. Investigating the properties of adhesive layers (adhesive function) used to stitch the multi-layers of the complex system and achieve the shock-resistant function.
5. Validating the optimal design by numerical simulations and experimental tests.
