Numerical Investigation of Transformation Field Analysis for Elastic-Plastic Periodic Materials

Resumo

Present work analyzes the numerical cost-benefit ratio of Dvorak’s Transformation Field Analysis to

evaluate elastoplastic behavior of periodically perforated metal sheets. The accuracy measurement and the process-
ing time are analyzed by implementing a finite element approach integrated with the Transformation Field Analysis

technique for different meshes and finite element orders. Numerical studies are employed to compare with standard
Finite Element Analysis for elastoplastic analysis of periodically perforated metal sheets. The numerical results
show the technique’s capabilities and favorable scenarios, besides the influence of domain discretization and finite
element order.
