where j = 1,2,..., n, n is the sum of the connection substructures
, [mathematical expression not reproducible] refers to the connection impedance matrix of the jth connection substructure
, o denotes the DOF sum of the jth connection substructure
, and [z.sub.ab] denotes the connection impedance between ath and bth DOFs that denotes the force needed to act on the bth DOF when the ath DOF happens to be a unit displacement.
The added substructure
in Figure 4(a) is composed of six nodes, and five of the nodes correspond to interface nodes.
Taking the velocity characteristic of the master side and slave side of [I.sub.1] as an example, a comparison between the frequency response result of conventional method and substructure
method was drawn.
Generally, in the substructure
modal synthesis method, the vibration system's kinematics equation is converted into modal coordinate space equation and the higher modes of the substructures
Divide each substructure
into several parts according to the force analysis.
The sections of the beams and columns of the megastructure and substructure
are both box sections.
In order to model the mechanical behaviour of such a variety of heterogeneous materials, the substructure
has to be simplified.
Since the nucleation of the twin-oriented domains takes place at the growth front of the crystal, the formation of the twin substructure
is possible only if the grain growth takes place in the <111>crystallographic direction.
CAS says that, for the first time ever with the click of a mouse, scientists can explore its collection of chemical information from journals and patents using a chemical substructure
. SciFinder SSM provides a unique view of chemical structure relationship integrated with the published research, right at the scientist's desktop.
Xing and Mita  proposed a substructure
approach to divide a complete structure into several substructures
so that damage detection processes can be independently conducted on each substructure
Consequently, the change in conditions of formation of condensates can be accompanied by the change not only in sizes of microstructural elements, but also in characteristics of their substructure
. It is necessary to take this into account in the development of a vapor-phase technology of creating of materials and coatings characterized by high values of mechanical characteristics.
These changes have caused an incompatibility with features specific to the substructure
searching capabilities of the Beilstein database as currently delivered on ORBIT.
