Maximum principal stress and deformation based on elasticity of two-dimensional plaque composite and fibrous cap thickness for non-calcified and calcified plaque. A: For a two-dimensional non-calcified plaque, graph of the maximum principal stress σ max versus Young modulus E lp and fibrous cap thickness d fc shows that critical stress is 370 kPa. B: For a two-dimensional calcified plaque at d cg = 0.02 mm, the fibrous tissue, lipid and calcium structures are present at various concentrations in the calcification agglomerate such that its Young modulus E cag varies from 10 to 400 kPa. The plot of σ max versus E cag and d fc shows that critical stress is 268.12 kPa. C: For a two-dimensional non-calcified plaque, graph of peak deformation D fc versus E lp and d fc shows that maximum deformation D max is 0.389 mm. D: For a two-dimensional calcified plaque, graph of D fc versus E cag and d fc gives D max = 0.239 mm.
