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

Table 2

Plastic-like energy (in J) dissipation for optimal stress yield (in MPa) for various locations of the adaptive element (instead of the elastic one) for different 10-element trusses: original (Figure 3(a)), remodeled for maximal stiffness (Figure 3(b)), and optimized by PSO (Figure 10(A)). is shown in Figure 11 for the cases marked with boldface.
