The Computational Structural Mechanics & Design (CSMD) Laboratory focuses on understanding and utilizing the mechanical behavior of solids and structures through advanced numerical analysis and design methods. Research areas include scientific machine learning (SciML) that integrates engineering insights into neural networks, multiscale and multi-physics analysis for non-traditional manufacturing processes such as additive manufacturing and advanced packaging, and the development of CAE-based design methods for novel design solutions, including topology optimization and data-driven generative design. The laboratory aims to simulate and design structures with inhomogeneities and distinctive topology, particularly for multifunctional materials used in soft robotics, adaptive structures, and bio-mimetic systems.

UNIST의 전산 구조 역학 및 설계(CSMD) 연구실은 첨단 수치 해석 및 설계 방법을 통해 고체 및 구조물의 기계적 거동을 이해하고 활용하는 데 중점을 둔다. 주요 연구 분야는 엔지니어링 통찰력을 신경망에 통합하는 과학적 머신러닝(SciML), 적층 제조 및 첨단 패키징과 같은 비 전통적인 제조 공정에 대한 다중 스케일 및 다중 물리 분석, 위상 최적화 및 데이터 기반 생성 설계를 포함한 새로운 설계 솔루션을 위한 CAE 기반 설계 방법 개발을 포함한다. 소프트 로봇, 적응형 구조 및 생체 모방 시스템에 사용되는 다기능 재료, 불균질성 및 고유한 토폴로지를 가진 구조를 시뮬레이션하고 설계하는 것을 목표로 한다.
