A review on the recent development in heterogeneous object modeling is provided in this
paper. General problems and prevalent solutions to the modeling of heterogeneous objects …

We investigate the effects of smoothness of basis functions on solution accuracy within the
isogeometric analysis framework. We consider two simple one-dimensional structural …

In the present work, a new spline based topology optimization using trimmed spline surfaces
and the isogeometric analysis is proposed. In the proposed approach, the trimmed surface …

In this work, an Isogeometric analysis for trimmed CAD surfaces in 2D linear elasticity
problem is presented. The main benefit of the proposed method is that no additional …

In most of structural optimization approaches, finite element method (FEM) has been
employed for structural response analysis and sensitivity calculation. However, the …

In recent years, various researchers have come up with different ways and means to
integrate CAD and CAM. Automatic feature recognition from CAD solid systems highly …

Recent advances in shape optimization rely on free‐form implicit representations, such as
level sets, to support boundary deformations and topological changes. By contrast …

We propose an automatic numerical method requiring minimal user intervention to simulate
delamination in composite structures. We develop isogeometric cohesive elements for two …

This paper presents the extension of the recently proposed NURBS‐enhanced finite
element method (NEFEM) to 3D domains. NEFEM is able to exactly represent the geometry …

During the last ten years, increasing efforts were made to improve and simplify the process
from Computer Aided Design (CAD) modeling to a numerical simulation. It has been shown …
