전산 구조해석 및 설계 연구실

Computational Structural Mechanics and Design

컴퓨터의 발전에 따라, 구조물의 설계에 있어 전산 기법의 활용은 빼놓을 수 없는 요소가 되었습니다. 그러나, 적층 제조물, 유연-미세 구조체등에서 발생하는 구조, 재료적 특이 거동은 종래의 기법으로는 그 이해와 설계가 곤란하며, 이는 해당 기술의 파급력을 저해하는 요소입니다. 해당 문제를 해결하기 위해, 전산 구조 해석 및 설계 연구실 (CSMD) 에서는 유한요소법, 분자동역학 전산모사, 이산요소법 등의 다양한 수치 해석기법과 더불어, 위상 최적 설계로 대표되는 구조체 설계 기법을 연구하고 더 나아가 이를 개선하기 위한 노력을 경주하고 있습니다.
The overarching research theme of Computational Structural Mechanics & Design (CSMD) Lab is to understand and harness the mechanical behavior of solids and structures with the aid of numerical analysis and design. In particular, we are actively thrusting the following technical areas, but not limited to:
1. Multiscale and multi-physics analysis of additive manufacturing process
2. Multiphysics topology optimization of large-deforming body
3. AI-driven acceleration of structural analysis and design
4. Improvement of the states-of-the-art numerical structural analysis method
We believe that these are particularly important in multifunctional materials (aka smart), which are prospect game-changers in soft-robotics, adaptive structures, and bio-mimetic systems. To this aim, we are developing and integrating computational methods to simulate and design structures with inhomogeneities and distinctive topology with the ever-increasing computing power.
