Title:
PERIDYNAMIC METHOD HAVING ADDITIONAL MIRRORING NODE, AND NUMERICAL ANALYSIS APPARATUS USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/135439
Kind Code:
A1
Abstract:
A peridynamic method having an additional mirroring node, according to embodiments of the present invention, comprises: a first step of calculating a shape tensor of a first node; a second step of calculating a force state vector of each of the first node and a plurality of second nodes by using the shape tensor; and a third step of calculating a peridynamic motion equation of the first node by using the force state vector. The first node is located at a boundary of a structure and has a horizon area of a predetermined size, the plurality of second nodes is in the horizon area and includes one or more third nodes, and the third node is a second node having no node at an origin-symmetric point on the basis of the first node among the plurality of second nodes. In the first step, the shape tensor is calculated by using origin-symmetric position values of the third nodes on the basis of the first node.
