The brightest trait of the degenerated virtual laminated element is virtual lamination, so the calculation of the stiffness matrix can be divided into different blocks and different materials, and the blocks with no material are virtual blocks, the stiffness of which are set to be zero.
Hence, since an element could contain multiple materials or even no material, the work is much easier when we separate the structure into elements, especially for complicated structures such as box girder, the number of elements can be remarkably reduced.
The formula to calculate the stiffness matrix of an element containing various materials is as follows: (2) In the formula, is the number of material types, is the Jocobi determinant of the coordinate transverse matrix for the very block.

Hierarchical architecture of Nacre Ultra-hard intermetallic borides such as AlMgB14 belong to the class of diamond materials by offering extreme hardness, wear resistance and chemical stability [11].
As a result, new advances in the applications of ultra-hard materials for tools and bioinspired structures can be expected.
