Description

Spall damage or fracture is caused by intensive tensile stress pulse within a solid which has been impacted by a high velocity projectile. This damage, microvoids or microcracks distributed within thin layer of the solid, are usually evaluated by destructive means, that is, cutting the samples and observation by SEM or an optical microscope [1–3]. This method requires laborious works. Essentially, with such destructive means we can not monitor the spall damage evolution under repeated impacts on single sample.
