ESDU 85031: Crack Resistance Curves
Input
Summary

ESDU 85031 provides R-curves for several aluminium, steel and titanium aerospace sheet materials in SI and British (lbf, in) units.

This Toolbox App is provided to interrogate the database of R-curves according to material type, specification, heat treatment, orientation and additional criteria such as thickness and width. The output from the Toolbox App consists of a summary of the input data and a plot of the chosen R-curve. The Δa' versus KR co-ordinates of the R-curve may be saved as either a CSV or a JSON file.
