摘要: 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, susceptibility non–visible or barely–visible impact damage is a significant constraint achieving optimum structural performance. Recent developments explicit finite element codes MSC.Dytran, LSDyna, Pam–Shock Radioss indicate that there considerable potential for the accurate prediction of transient dynamic behaviour onset critical structures. A series test cases has been developed investigate parameters associated with modelling stiffened panels large civil transport aircraft components.
