Figure 9

Finite element analysis of plaque models at two-dimensional cross-sections and with different fibrous cap thickness and calcification gap. Peak principal stress and deformation plots pertain to a constant lipid pool (E lp = 1 kPa) of fixed thickness (0.35 mm), and with varying fibrous cap thickness d fc and calcification gap d cg . A: For d fc = 0.05 mm, the critical stress σ cr and maximum deformation D max are 331 kPa and 0.390 mm respectively. B: For d fc = 0.48 mm, σ cr = 28.7 kPa and D max = 0.0281 mm. The geometrical outlines of the plaque composites for A and B show the structural difference in the deformed plaque due to applied stress. C: For d cg = 0.02 mm and d fc = 0.05 mm, σ cr = 282 kPa and D max = 0.290 mm. D: For d cg = 0.175 mm and d fc = 0.05 mm, σ cr = 326 kPa and D max = 0.370 mm.
