Topologically interlocked structures are architectured by fitting together blocks that constrained geometrically through contact and friction their neighboring blocks. As long as the frictional strength is nowhere exceeded, stick against each other, allowing for large rotations. Once interfacial stresses exceed strength, relative sliding between alters structure’s mechanical response. Improving...

To identify cracks in a structure, an inverse analysis has been performed using the static and dynamic response of structure. The accuracy is highly dependent on form objective function choice optimization method. Generally, method searching solution by gradient adopted. However, for crack problem interested this study, it known to have drawback that search strongly depends initial value settin...
