Stress intensity factor (SIF) calculation from crack tip displacements
The code implements Muskhelishvili's complex function approach to calculate 2D stress intensity factors (modes I+II) from crack tip displacement fields. Surface displacements can be used with a plane stress elastic model. The code uses power/Fourier series expansion and a conformal mapping of an ellipse onto a circle.
Simple console program intended for factor or principal components analysis. It calculates the optimal number of factors using the Horn's parallel analysis, computes the Kaiser-Meyer-Olkin and a few other measures of sampling adequacy.
