Abstract: At the present time, advanced composites have been widely accepted as engineering materials. Analysis techniques for the response of composite materials and structures to static loads are reasonably well established. Composite materials are susceptible to low velocity and low energy impact damage. Recently, the damage inflicted by such impact has been a subject of great interest. This paper primarily illustrates that it is possible to quantitatively assess damage due to any type of unexpected loading, including impact, using progressive failure finite element analysis.
