title: Application of nanoindenter in investigating properties of the cuticle of dung beetle.
abstract: The cuticle of insects is multilayered structure at positioning. A Berkovich tip was used for the tests. micro- or nano-scale in vertical direction. This work investigated the mechanical properties of the cuticle of dung beetle Copris ochus Motschulsky using nanoindenter. It was shown that the nanomechanical properties of the cuticle were different for each layer of the cuticle and its normal nanoindentation was resulted from the composite effect of the all layers.
