Figure 11:
Simulation of indentation of cylindrical sample made from Sylgard 527 gel shown in Figure 10. a) MTLED model consisting of 5,037 nodes and 25,050 integration points in undeformed configuration. The prescribed displacement was applied at the nodes shown in red colour. The nodes shown in green were rigidly constrained. b) Finite element (we used a non-linear static procedure with direct solver from ABAQUS finite element code) consisting of 5037 nodes and 25050 four-noded hybrid tetrahedral elements (elements C3D4H in ABAQUS) in undeformed configuration. The boundary conditions are the same as for the MTLED model.
