Designing of Elastoplastic Adaptive Truss Structures with the Use of Particle Swarm Optimization

Figure 3

(a) Original structure: the two leftmost nodes are fixed and the node where impacting mass  kg with the velocity  m/s is marked with the arrow. (b) Remodeled structure which maximizes the stiffness (at the impact node at  ms). Here and in the subsequent figures, diamonds denote fixed points, filled circles represent the nodes, and a square marks the node where the impact takes place. The width of the lines representing elements is proportional to their cross section.
