SUMMARY Enforcing essential boundary conditions plays a central role in immersed methods. Nitsche's idea has proven to be reliable concept satisfy weakly and interface constraints. We formulate an extension of method for elasticity problems the framework higher order continuity approximation schemes such as B‐spline non‐uniform rational basis spline version finite cell or isogeometric analysis on trimmed geometries. Furthermore, we illustrate significant improvement flexibility applicability...
Articular cartilage from a material science point of view is soft network composite that plays critical role in load-bearing joints during dynamic loading. Its structure, consisting collagen fiber and hydrated proteoglycan matrix, gives rise to the complex mechanical properties tissue including viscoelasticity stress relaxation. Melt electrospinning writing allows design fabrication medical grade polycaprolactone (mPCL) fibrous networks for reinforcement hydrogel matrices engineering....
In many extended versions of the finite element method (FEM) mesh does not conform to physical domain. Therefore, discontinuity variables is expected when some elements are cut by boundary. Thus, integrands continuous over whole integration Apparently, none well developed schemes such as Gauss quadrature can be used readily. This paper investigates several modifications capture within an and perform a more precise integration. The here cell (FCM), extension high-order approximation space...
We present a design rationale for stretchable soft network composites engineering tissues that predominantly function under high tensile loads. The convergence of 3D-printed fibers selected from library and biodegradable interpenetrating polymer networks (IPNs) result in biomimetic tissue engineered constructs (bTECs) with fully tunable properties can match specific requirements. our technology platform using an exemplary composite model is characterized to be flexible, yet ∼125 times...
Selective Laser Melting (SLM) technology has undergone significant development in the past years providing unique flexibility for fabrication of complex metamaterials such as octet-truss lattices. However, microstructure can exhibit variations due to high complexity manufacturing process. Consequently, mechanical behavior, particular, linear elastic response, these lattices is strongly dependent on process-induced defects, raising importance incorporation as-manufactured geometries into...
Abstract In this paper we present an implementation of a three‐dimensional p ‐version for structural problems solids with almost arbitrarily curved surfaces. Applying the blending function method, complex structures can often be modelled by few ‐elements, being basis higher order approximation. Numerical examples will demonstrate, that anisotropic Ansatz spaces allows to predict behaviour plates and shells approximately same amount degrees freedom as in two‐dimensional case, yet...
SUMMARY The finite cell method (FCM) combines the fictitious domain approach with p ‐version of element and adaptive integration. For problems linear elasticity, it offers high convergence rates simple mesh generation, irrespective geometric complexity involved. This article presents integration FCM into framework nonlinear technology. However, penalty parameter is restricted to a few orders magnitude in order maintain local uniqueness deformation map. As consequence weak penalization,...
