Webcrystal, any solid material in which the component atoms are arranged in a definite pattern and whose surface regularity reflects its internal symmetry. The definition of a solid appears obvious; a solid is generally thought of as being hard and firm. Upon inspection, however, the definition becomes less straightforward. A cube of butter, for example, is hard after … WebAbstract. The finite element method provides a powerful complement to polycrystal plasticity theory for analyzing the deformations of polycrystalline solids. Anisotropy of the flow can be computed based on the slip characteristics of individual crystals and included in finite element formulations as the constitutive description of the material.
