Figure 3. Stress patterns in the middle 4 mm for the models with lateral attachment (models in top row) and top and bottom attachment (models in bottom row). For each of the models, the applied loads were the loads at fracture (Table). These loads were also applied for top and bottom attachment (bottom-row models). For lateral attachment, maximum major principle stresses were localized at approximately 0.2 mm from the fixed sites and were 70.8, 64.2, 56.0, 62.2, and 65.0 MPa (upper row from left to right). For top and bottom attachment, the major principle stresses were 44.3, 27.7, 19.0, 38.7, and 36.5 MPa (bottom row from left to right). The triangles and arrows indicate the stationary and moving sides of the models, respectively.
