Ti-alloy panels consisting of a honeycomb or a corrugated sheet sandwiched between two skins are widely used in aerospace where they may be subjected to impulsive loading. The tests described aim to reproduce the parameters governing the impact behaviour of such panels. Emphasis is placed on three types of tests : shear, compression, and bending. The apparatus and instrumentation are described as well as the significance of some of the experimental results.
