Isogeometric shape sensitivity analysis [PDF]
WIT Transactions on The Built Environment, 2012 On a regular basis, engineering analysis requires stating and solving systems of partial differential equations (PDEs). The most powerful and widely extended techniques for solving PDEs are the so-called Weighted Residuals Methods. To this group belong, among others, the Finite Element Method (FEM), the Boundary Element Method (BEM), the Finite Volume ...

International Journal of Mechanical System Dynamics, Volume 5, Issue 3, Page 535-563, September 2025.ABSTRACT This article investigates the nonlinear vibration behavior of porous multidirectional piezoelectric functionally graded nonuniform (PFGN) plates resting on orthotropic variable elastic foundations and subjected to hygrothermal loading. The sigmoidal law is employed to define the multidirectional gradation properties, incorporating porosity ...

, 2018 We present a class of spline finite element methods for time-domain wave propagation which are particularly amenable to explicit time-stepping. The proposed methods utilize a discontinuous Galerkin discretization to enforce continuity of the solution ...

Generalized B-Splines in Isogeometric Analysis [PDF]
, 2017 In this paper, we survey the use of generalized B-splines in isogeometric Galerkin and collocation methods. Generalized B-splines are a special class of Tchebycheffian B-splines and form an attractive alternative to standard polynomial B-splines and NURBS in both modeling and simulation.

International Journal for Numerical Methods in Engineering, Volume 126, Issue 16, 30 August 2025.ABSTRACT In this work, we compare the nodal and isogeometric spatial discretization schemes for the nonlinear formulation of shear‐ and torsion‐free rods introduced in Gebhardt and Romero (see Reference no. 31). We investigate the resulting discrete solution space, the accuracy, and the computational cost of these spatial discretization schemes.

Spline‐Based Framework for Microscopic Contact Zone Modeling in Lubricated Orthogonal Cutting
International Journal for Numerical Methods in Engineering, Volume 126, Issue 14, 30 July 2025.ABSTRACT Accurately predicting the coefficient of friction between tool, chip, and workpiece during machining is essential for a reliable and cost‐effective process. In this context, current numerical methods are often based on homogenized approaches with friction models that use constant friction coefficients; thus, failing to capture local effects ...
