Applicability of inverse analysis to obtain the tensile behavior of bamboo bioconcretes

Resumo

In view of the difficulties in obtaining traction laws in the experimental field, it is of the utmost importance to adopt alternative tools to overcome this problem. Thus, this work is a brief manual for obtaining tensile laws using numerical modeling, which describes the steps for obtaining them, from defining the fixed parameters of the numerical model to characterizing the material's tensile mechanical behavior. The DIANA® software was used to run the numerical simulations and the numerical model calibration was based on average results of experimental curves. The target material for this study is a new bamboo bioconcretes developed by researchers at COPPE/UFRJ. The results show that the traction laws developed through inverse analysis using numerical modeling are highly accurate compared to experimental responses. The calibration of the numerical model makes a significant contribution to the quality of the results. Among the evaluated tensile models, the ones that best reproduce the experimental behavior of the bamboo bioconcrete are the multilinear and exponential models.
