Our recent paper, titled "Impact Behavior of Periodic, Stochastic, and Anisotropic Minimal Surface-Lattice Sandwich Structures," is now available online. In this study, we examined how the topology of minimal surface-lattice cores affects the perforation limit and impact-damage behavior of composite sandwich structures. We proposed innovative methods for designing composite sandwich structures that are more damage-tolerant and resistant to perforation. This research greatly benefited from the significant and invaluable contributions of Dr. Imad Barsoum and Prof. Rashid Abu Al-Rub, whose deep expertise in the field was instrumental.

Our paper "Novel compliant mechanism-based auxetic metamaterial: Kinematic and experimental analysis" is now available online! 💡 In this work, we developed a unique auxetic metamaterial obtained from the compliant version of the 10-link 1DoF mechanism and verified its Poisson’s ratio through kinematic analysis, Finite Element modeling, and experimental tests. Our study highlights how the motion capabilities of linkages can be used to produce metamaterials with specific displacement responses. Hence, modifying unit cell dimensions and arrangements can tune auxetic responses, demonstrating the potential of using compliant mechanisms in the design of metamaterials. This article is now published in the International Journal of Mechanical Sciences from Elsevier!

Excited to share my latest achievement: the publication of my second research paper titled "A Non-Iterative Boundary Element Formulation for Nonlinear Viscoelasticity" in the Journal of Engineering Analysis with Boundary Elements, building on the foundations of my PhD thesis. The work is co-authored with Dr. Serdar Göktepe and Dr. Ercan Gürses. Highlights of our work include: 🔹 Development of a non-iterative time-domain BEM approach for nonlinear viscoelasticity. 🔹 Implementation of a computationally efficient semi-implicit update method for history variables. 🔹 Non-iterative time-stepping achieved through consistent linearization of evolution equations. 🔹 Utilization of domain integrals via truly mesh-free integration techniques. 🔹 Comprehensive assessment through comparison with fully implicit nonlinear FEM methods.

#100daysamplifierdesign day 28 I read a research paper on Antiferromagnetic Films and Their Applications The research starts with a comprehensive literature review, dicussing the current status, challenges, and potential of spintronics, particularly focusing on replacing nanoelectronic devices with spintronic ones. It talks about the need for new materials in spintronic devices to overcome limitations in miniaturization and efficiency. The study also discusses recent developments in the three types of antiferromagnets with their properties and potential applications. Furthermore, The study investigates spin-orbit torque (SOT) and spin caloritronic effects, such as anomalous Hall and spin Hall effects, spin Seebeck and Nernst effects, and their potential applications in spintronics. It discusses experimental techniques and theoretical models to understand and quantify these effects in AF materials. The study however does not completely put into consideration the physical limitations in real life applocation. It is also a bit complex and it took me time to digest the research paper.

Hello Everyone, I am excited to share my first research paper on High-Speed Digital Design that was accepted by the International Journal of Scientific Development and Research (IJSDR) I have been interested in signal integrity and PCBA since my academic beginnings and got the opportunity to work and apply my knowledge in the same industry. With that knowledge, I recently completed my research about "When Signal Changes the Plane and its Mitigation Methods". In this paper, I have simulated the stack up (S-G-G-S) using Ansys software and demonstrated the significance of cavity noise and other important parameters that result in signal integrity issues in High-Speed Digital Design. I want to thank my co-authors Gauriech Ishaan Pilla and Bhargav Chauhan as contributors during this research and publication. After working actively for over 3 months, I was finally able to get submissions acceptance as per the IJSDR publication guidelines. I would further like to share my gratitude to Dr. Melinda Piket-May and Dr. Eric Bogatin for their teachings, guidance, and support related to Signal Integrity and High-Speed fundamentals. I would appreciate it if you could provide your valuable feedback as that will help me constantly learn and improve. I am also open to feedback from industry experts and their thoughts on what you think about this article. Is this relevant to your field? Feel free to use this article if you find it useful and if it supports any of your research in High-Speed Digital Design and Signal Integrity Concepts.

Recently, the article "Optimization of acoustic porous material absorbers modeled as rigid multiple microducts networks: Metamaterial design using additive manufacturing” was published by MOPT/LVA's researcher Olavo M. Silva! 👨🏻💻 The work was developed along side with the reserachers Paulo H. Mareze, William D’A Fonseca, Eric Brandão and Luís Godinho, portraying the partnership with UFSM (Universidade Federal de Santa Maria) and Universidade de Coimbra (Portugal). 🤝🏻 📄 Here’s the abstract about the work: This research presents a strategy to enhancing sound absorption in porous acoustic metamaterials through the optimization of micro-duct networks. The study employs a combination of analytical and numerical methods, systematically adjusting micro-duct diameters within a 2D grid to optimize absorption coefficients at specific frequency bands. [...] This study contributes to both theoretical understanding and practical application in acoustic material design, emphasizing the potential for customizing materials to specific frequency ranges. The integration of FETM modeling with MMA provides a systematic and effective approach for optimizing acoustic materials, particularly in enhancing absorption at lower frequencies. 🔎 📌 Follow the link to read the full article: https://lnkd.in/dDTQWSVP
