Summary
Advanced fibre composite materials are now widely used in aerospace structures due to their superior performance characteristics such as high specific strength and stiffness. However, their susceptibility to non–visible or barely–visible impact damage is a significant constraint in achieving optimum structural performance. Recent developments in explicit finite element codes such as MSC.Dytran, LSDyna, Pam–Shock and Radioss indicate that there is now considerable potential for the accurate prediction of transient dynamic behaviour and onset of critical impact damage in composite structures. A series of test cases has been developed to investigate the critical parameters associated with the modelling of composite stiffened panels used in large civil transport aircraft components.
