  • Crack analysis by finite element method based on explicit method including modified incremental technique

抄録

<p>The authors have developed finite element analysis (FEA) program based on explicit method including modified incremental technique in order to shorten CPU time in material non-linear problem with cracking. Also, introduction of the method can be expected to improve convergence and stability of the problem. In this paper, we demonstrate the computational algorithm of the FEA program and verify the validity through a few numerical examples. In addition, we show its accuracy and CPU time in comparison with numerical results obtained from existing FEA programs, which have been developed be authors.</p>
