Description
|
This dataset contains the MATLAB code used to determine the elasto-plastic fracture toughness following the four different JR-curves construction approaches described in Fernandez-Pison et al. (2021). Additional files containing the data from an actual fracture toughness test are included (they are used as inputs in the main MATLAB code).

Notes
| ** Procedure: 1st: Save the load-line displacement and load data of your fracture toughness test in the corresponding rows of the EXCEL file 'J_Calculation_DATA.xlsx'. 2nd: Run the MATLAB code 'J_Calculation_INPUT.m'. Some inputs are automatically asked to the user by dialog boxes, others are directly imported from the EXCEL file. The MATLAB data 'J_Calculation_INPUT.mat' is automatically generated (the old one will be overwritten). 3rd: Run the MATLAB code 'J_Calculation_ANALYSIS.m'. The inputs are automatically loaded from the MATLAB data. The results will be automatically available by means of figures and comments in the command window.
