1. Introduction
In the last years nanomaterials have been the subject of many investigations and publications [1]. One of the features of these materials, which is best examined and described, is their mechanical behavior [2]. It is commonly known that compared with their microcrystalline counterparts, nanomaterials are characterized by higher values of the yield stress, tensile strength, and hardness, whereas their plasticity and fracture toughness are lower [3]. Another basic parameter which describes the mechanical behavior of materials is their modulus of elasticity – E. In the case of nanomaterials there are however some problems with determining the elastic modulus. The possible relation between the value of this modulus and the structure of nanomaterials is difficult to describe. This is so since thesematerials are fabricated by various methods, various types of samples are prepared for their examinations, and various methods are employed for measuring their properties. Thatthe results obtained thus far are not unequivocal can result from the fact that there are a variety of factors which affect the value of the elastic modulus in a given nanomaterial.
