“…Although the GTO methods (e.g., the MMA-based framework) exhibit higher computational efficiency than the NGTO methods, they more depend on the selected initial designs with existing BGs. Very recently, Hu et al [141] proposed a novel gradient-based optimizer, i.e., the Trust Region based Moving Asymptotes (TRMA), which showed stronger robustness than the frequently used MMA in solving some benchmark topology optimization problems (like stress-constrained problems).…”

“…This iterative inner solve, which can be significantly expensive, determines the update of the design variables. Several MMA-based approaches have been developed, such as the GCMMA [111], which guarantees the convergence of the algorithm, the TRMMA [60], which presents improved Chapter 4. Toward Large-Scale GPU-based Stress-Constrained Topology Optimization 44 convergence, and the EMMA [21], which incorporate second order information, but none of them address the high computational cost.…”

I would like to thank my advisor Prof. Ivan Fábio Mota de Menezes for whom I have nothing but the most profound admiration. Thank for all your support, and for being a wonderful role model throughout these years. More than an advisor, I consider you a dear friend that I hope to keep for the rest of my life. I also want to thank Prof. Glaucio Paulino who also had a central role in advising me through my PhD, your passion and dedication has truly inspired me to become a better version of myself. Thank you for believing in me, and for providing essential guidance in this journey. I would like to thank the members of my committee Prof. Anderson Pereira, Prof. Americo Cunha, and Prof. Emilio Silva for taking the time to read my work, and for their insightful comments, suggestions, and discussions, that helped improve the quality of my work.Outside of the academic field, but not less important, I want to thank my parents Fernando Rocha da Senhora, and Denise Bezerra Vasconcelos da Senhora, my brother Leonardo Vasconcelos da Senhora, and all my family (which is too extensive to name here). Your love and support is what made this possible. I also want to thank all my friends for brightening up my days, and making life more colorful and cheerful. I hope you all know how much you mean to me.

Metamaterials (MMs), which include phononic crystals (PCs) as a particular type, exhibit anomalous wave propagation properties through artificial design of topologies or lattice forms of unit‐cells. Recent advancements in MMs signify an ascendant research trend, providing promising design ideas and means for unprecedented wave propagation properties. The imperative for on‐demand, real‐time active control of wave propagation underscores the significance of tunable manipulation of acoustic/elastic waves, promoting the design and development of tunable MMs. Furthermore, the versatility of intelligent materials and their ongoing development and innovation contribute significantly to the emergence of diverse intelligent MMs. This comprehensive survey provides an overview of recent advancements and current research trends in the interdisciplinary field of intelligent MMs with electro‐/magneto‐mechanical couplings. The primary objective of the review is to emphasize significant progress in agile manipulation of acoustic/elastic waves in electro‐/magneto‐mechanical coupled MMs, followed by an in‐depth exploration of intelligent metasurfaces, topological MMs, non‐Hermitian parity‐time symmetric wave systems, odd elastic MMs, and spatiotemporally modulated MMs. Special emphasis is given to multi‐field coupling effects. The review concludes with a summary and outlines potential prospects, offering a timely and informative guide for future studies on actively tunable PCs and MMs in practical engineering applications.
