MS19 - Optimization Methods in Structural Mechanics: Numerical Models and Applications

Non-Smooth Contact Dynamics (NSCD) is a well-established method for the dynamic analysis of rigid bodies and has recently been extended to historical masonry structures, where the arrangement of units has a strong influence on the global response. While most of the existing formulations assume prismatic block geometries, several historical structures are composed of elements with curved shapes...

36. Onset of yielding in imperfect lattice structures: an Upper-Bound Limit Analysis framework

MS19 - Optimization Methods in Structural Mechanics: Numerical Models and Applications

Lattice structures are widespread in natural systems at the microscopic scale and are increasingly adopted in engineering applications at multiple scales due to their high strength-to-weight ratio and energy absorption capacity. The reliable assessment of their load-bearing capacity is therefore essential for safe design and must account for both geometrical and mechanical imperfections...

162. On multistable beam-lattice structures

MS19 - Optimization Methods in Structural Mechanics: Numerical Models and Applications

Interest in beam-lattice metamaterials is growing nowadays. They mimic classic crystalline lattices and exhibit promising properties, including low weight, enhanced flexibility, and efficient energy absorption. In the analysis of beam-lattice metamaterials, instabilities analogous to the classical Euler instability are often anticipated. For instance, in elastomeric open-cell foams, such...

72. Optimal vibration control in structures equipped with Active Mass Dampers

MS19 - Optimization Methods in Structural Mechanics: Numerical Models and Applications

Active vibration control through Active Mass Dampers (AMDs) represents an effective and increasingly widespread strategy for reducing the dynamic response of civil structures subjected to actions such as wind, earthquakes, and other induced dynamic loads, both in the design phase of new buildings and in the retrofit of existing structures.
However, the performance of such systems does not...
