Figure 3 Effect of lipid core on stress distribution. The arrow indicates the point of stress concentration at a localized surface area just above the lipid core (A2). The size of the lipid core did not influence the value of the surface stress (B2), provided the fibrous cap thickness remained constant. (A1, B1) Plaque models used. (A2, B2) Mapping of stress distribution of the corresponded model.
