Critical stress on fibrous cap with respect to width of calcification gap and maximum deformation on fibrous cap for three-dimensional plaque rupture analysis. A: The plot of critical stress σ cr versus width of calcification gap d cg shows that calcification gap value of > 0.21 mm causes stress levels to exceed 300 kPa and cause plaque rupture. B: Critical stress σ cr versus maximum deformation D max of fibrous cap for d fc at 0.05 mm demonstrates that D max > 0.168 mm causes plaque rupture.
