“…5, in which the minimal mesh quality is 0.02, 0.04, 0.07, 0.17 and 0.15 respectively. The grid-based method [26,27] is one of the most widely used methods, which is suitable for any shape of solid model, and can obtain high quality internal mesh and low quality surface mesh. The following two examples of mesh smoothing are performed for hexahedral meshes generated by grid-based method.…”

“…The adaptive element mesh can be created using geometric features of the problem or using a calculated indicator [13]. In geometric adaptive methods, refinement is done through points, edges, and surfaces on the element depending on the characteristics of the problem geometry [14].…”

The use of hyperelastic materials capable of large deformations, such as elastomeric bearings used to reduce seismic effects, is quite common in civil engineering. Such environments are, in most cases, addressed by numerical solution techniques such as the finite element method. In case of large deformations, nonlinear analysis is used in the solution. In the study presented here, large deformations of a hyperelastic continuum expressed by the Mooney-Rivlin material model are calculated using hexahedral adaptive finite elements. A code was written in MATLAB using the total Lagrangian formulation for the nonlinear adaptive finite element solution. Comparisons were made with Abaqus software to check the consistency of the results obtained from this program. It has been observed that local refinements in the adaptive element mesh occur in the regions where they are needed. Considering the variation of maximum displacement and maximum stress with the number of elements, it has been observed that mesh refinement creates a convergent solution.

“…Hexahedral elements were considered to solve the issue of ill-shaped elements. [20][21][22][23][24][25][26][27][28] Methods based on hexahedral meshes will not introduce ill-shaped elements, but the surfaces caused by cutting need to be reconstructed.…”
