Description

Advanced composites, particularly high modulus laminates, are often susceptible to transverse impact loading. The major damage introduced due to low velocity impact includes matrix cracking, fiber break and delaminations. Such flaws tend to reduce residual strength of the material and may cause structural failure when the material is subjected to higher operating loads [1,2]. Unfortunately, such a damage cannot be observed on the surface until failure; hence, structural integrity should be assessed by nondestructive evaluation (NDE) methods at the earliest possible stage.
