ON A DISCRETE MODEL OF LATTICE STRUCTURE
一类网格结构模型的研究

In this paper a class of discrete models are proposed which are suitable to evaluate a variety of two-dimension lattice structures. The research object of the model is the node of lattice, and its governing equations are related to the number of bars connecting with the node and the geometry. If only some types of governing equations of essential nodes are presented, the evaluation of cellular solids can be processed for every type of lattice with a corresponding type node. The form of this model is simple and easy to carry out by computer.
