Implementation of a Hierarchical Wedge Element in the Self-Adaptive Finite Element (Fe) Program Stripe

摘要

A three-dimensional self-adaptive finite element (FE) method in linear elastomechanics is considered. A wedge-shaped finite element with hierarchical interpolation functions based on the p-version of the finite element method is derived. This element is implemented in the self-adaptive FE-program STRIPE and is fully compatible with the previously implemented brick-shaped finite element. The characteristics of the element are demonstrated by solving examples.
