연구실 소개
윤정환 교수의 연구실은 유한요소 해석 기반의 첨단 구조해석 기법을 개발하고 있으며, 특히 두꺼운 두께의 얇은 구조물에 적합한 고정밀·고효율의 고체-쉘 유한요소 요소(RESS)를 핵심으로 연구를 진행하고 있습니다. 대변형, 비선형 플라스틱 거동을 고려한 해석 기법과 함께, 복잡한 접촉 문제 및 빠른 수렴성을 확보하기 위한 강건한 수치적 통합 기법을 개발하고 있습니다. 이는 자동차, 항공우주 등 고성능 구조물의 설계 및 해석에 응용 가능합니다.

Enhanced assumed strain (EAS) and assumed natural strain (ANS) methods for one‐point quadrature solid‐shell elementsRui P.R. Cardoso, Jeong Whan Yoon, Made. Mahardika, Sanjay Choudhry, Ricardo J. Alves de Sousa, Robertt Valente
SJR Q1International Journal for Numerical Methods in EngineeringOA
Abstract A reduced enhanced solid‐shell (RESS) finite element concept has been suggested recently by Alves de Sousa et al. ( Int. J. Numer. Meth. Engng 2005; 62 :952; Int. J. Numer. Meth. Engng 2006; 67 :160; Int. J. Plasticity 2007; 23 :490). Developments on the ‘RESS’ element were motivated by the following reasons: first, solid‐shell elements automatically incorporate the normal stress along the thickness direction, which makes them more suitable for the simulations with double‐sided contact
