Coupling flat-top partition of unity method and finite element method
چکیده انگلیسی

We present a novel technique of coupling finite element method with mesh-based flat-top partition of unity method. The proposed coupling method allows us to bind any order of finite elements with flat-top partition of unity method. To verify the coupling, we test the coupling method on one- and two-dimensional boundary value problems including linear elasticity problem on a cracked domain. The coupled formulation provides a platform for stable enrichments to obtain highly accurate solution especially in the enrichment area.


► Seamless coupling between flat-top partition of unity method and finite element method.
► Consistent polynomial reproducing order on the coupled domain.
► Flexible enrichment zone and enrichment order.
