Computational Advanced Nanomechanics (CAN)


관련기사 바로가기

CAN is investigating various characteristics of nanoscale materials using computation, specially emphasizing on the mechanics or mechanics-mediate characteristics of them. CAN is studying the validity and limitation of continuum (solid) mechanics theories in the applications for nanoscale materials. In addition, CAN is working on traditional CAE using FEM for various applications such as batteries, electronic skin, auxetic materials, acoustic topological insulators and so on.
