Fig. 28: Comparison of envelope curves with different kφ with l/h = 1, l = 0.01 mm and yc = 0.004 mm
 

The error e^num_Γ (Eq. 61) of the numerically obtained crack length in a 2D simulation with a transformed phase-field ansatz in comparison to the expected solution of 0.1mm and 
the error  e^num_Γlς (Eq. 62) of the numerically obtained crack length in a 2D simulation with a transformed phase-field ansatz in comparison to the theoretically expected (analytical) crack surface when the stabilization is regarded
is plotted over different kφ.

The simulation setup is given in Fig. 26, the position of the crack yc is enforced with a penalty formulation.
