Review of Loads Transfer Laws and their Applications in Artillery XIAO Hui1, a, YANG Guolai2,b and WANG Peng3,c 1, 2,3 School of mechanical engineering, Nanjing University of Science and Technology, Nanjing 210094, P.R.
In essence, to continuum topology optimization, no matter which is the objective function, weight or flexibility, the optimal results are to find the best transmission path and the optimal material stiffness distribution.
FIG.2 The procedure of OptiStruct Optimal Design The idea of topology optimization design is to transform the problem of seeking optimal structure topology distribution into the problem of seeking optimal material distribution, which is under the conditions of given material quality and design domain.
So the substance of the material distribution is the best transmission path. 4.2 Loads transfer optimization based on Multi-body dynamics We can apply the virtual prototyping technology in artillery firing dynamics, and use ADAMS to analyze loads.

A polymeric material with a laminin-apatite composite layer on its surface should be a promissing candidate as an ideal skin terminal, because apatite provides the material with good biocompatibility [3], whereas laminin, which is a cell adhesion molecule for epithelial cells, provides the material with strong skin-adhesiveness [4].
Title of Publication (to be inserted by the publisher) Materials and Methods Preparation of specimens.
This kind of composite material has great potential as a skin terminal with improved adhesiveness to skin tissue as well as good biocompatibility.

Port, as the location of intended interaction, plays an important role in the configuration design, which abstractly represents the intended exchange of signals, energy or material in a convenient way.
The external ports denote the energy, material or signal interfaces between a component and its environment.
