Newmark's schemes and Isogeometric approximation of acoustic waves with absorbing boundary conditions [PDF]
, 2017 In recent years there has been an increased attention to the accurate simulation of wave propagation in acoustic models. Classic simulations of acoustic waves propagation in geophysics have been based on finite difference or finite element methods also ...

Isogeometric Analysis: Higher-Order Differential Equations [PDF]
, 2013 This thesis introduces Isogeometric Analysis as a potentional bridge between the Finite Element Analysis (FEA) and Computer Aided Design (CAD) communities. An introduction to B-splines and B-spline-based Isogeometric Analysis is given.

Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel
Advanced Materials Technologies, Volume 11, Issue 1, 8 January 2026.The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.

Material Identification of Heterogeneous Isogeometric Bernoulli–Euler Beams With Pretensioning
Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 4, December 2025.ABSTRACT This study employs the Finite Element Model Updating (FEMU) method for identification of material parameters and pretensioning forces in heterogeneous planar Bernoulli–Euler beams, which are analyzed using isogeometric analysis. The unknown material fields are discretized with a separate mesh based on Lagrange interpolation, referred to as the

Physical structural assessment of a segmented concrete shell building floor prototype
Structural Concrete, Volume 26, Issue 6, Page 8419-8436, December 2025.Abstract To reduce the significant environmental impact of the construction industry, building floors designed as concrete shells that work mainly in compression and that are segmented for prefabrication and disassembly offer a promising alternative to reinforced thick flat slabs.

Higher‐Order, Mixed‐Hybrid Finite Elements for Kirchhoff–Love Shells
International Journal for Numerical Methods in Engineering, Volume 126, Issue 21, 15 November 2025.ABSTRACT A novel mixed‐hybrid method for Kirchhoff–Love shells is proposed that enables the use of classical, possibly higher‐order Lagrange elements in numerical analyses. In contrast to purely displacement‐based formulations that require higher continuity of shape functions as in isogeometric analysis (IGA), the mixed formulation features ...
