Extraction of fracture mechanics parameters from fem analysis: algorithms and procedures. Bachareva Y.N., Mironov A.V., Petrova D.M. expresses deep gratitude for financial support the Russian Foundation for Basic Research (project No. Key words: crack-tip fields, over deterministic method, finite element analysis, higher order terms, multi-parameter stress field presentation, digital photoelasticity, digital image processing.Īcknowledgments: Bakhareva Yu.N. Explanation has been made for giving guidance to a user on how best to approach implementation of the method from a practical standpoint. The principal stresses obtained from finite element method are in good agreement with the isochromatic fringe patterns obtained by the photoelasticity method. The results of finite element analysis are compared with the digital photoelasticity experiments. Examples are presented for crack-tip fields recorded using digital photoelasticity.
The methodology is illustrated and applied to several cases of cracked specimens.
The technique is aimed at the determination of coefficients of the Williams series expansion from finite element analysis and is based on the over deterministic approach. The algorithms and procedures based on multi-parameter stress field representations in series form are shown to be a powerful tool for reliable and accurate parameter determination.
The multi-parameter crack tip stress field description is used. The paper describes new algorithms and procedures proposed for determining fracture mechanics parameters from finite element analysis using the over deterministic method.
