Figure 3 Encapsulated soft tissue, bone, and ligament construction and plantar contact area of the finite element foot modelThe models of soft tissue, cartilage, bone, and ligament were imported into ABAQUS software to simulate the foot model. Then, plantar response in the stance phase was simulated by fixing soft tissue of the tibia and fibula. (A) Grid size chart of encapsulated soft tissue; (B) grid size chart of the bone tissue; (C) schematic diagram of foot ligament; and (D) diagram of model contact area in stance phase.
