Unformatted text preview: need be modeled. The height (and width for HYPER86) of the elements in the finite element model is chosen such that the elements have a reasonable aspect ratio. Only radial degrees of freedom are active. The total pressure is applied in two load increments. To approximate incompressible behavior, Poisson's ratio is set close to 1/2 (0.49) and reduced integration is requested. Temperature-dependent properties are used in the HYPER84 portion solely for verification purposes. Note that the only radial displacement is reported as a verified result for HYPER58. The location of the centroid of the HYPER158 tetrahedron is different than HYPER84 and HYPER86, which are bricks.
