We present a mixed integration point (MIP) formulation for hyperelastic isogeometric
Kirchhoff–Love shells. While previous works have proposed mixed integration point …

A new solid-shell finite element formulation is investigated in this paper. Departing from the
S-FEM concept of node-based stress smoothing scheme, a new pattern that introduces new …

The multi‐modal Koiter method is a reduction technique for estimating quickly the nonlinear
buckling response of structures under mechanical loads requiring a fine discretization. The …

An efficient continuation method is proposed for a direct sensitivity analysis of the critical
point to geometrical imperfections, eg expressed as combination of given shapes, for thin …

In soil slope stability, locating the critical slip surface with the minimum safety factor is a
difficult and complicated optimization problem. Most methods fail when proper bounds are …

Not all imperfections are detrimental in buckling problems. A recent design paradigm,
termed modal nudging, utilizes geometric “imperfections” with negligible self-weight change …

This paper presents an efficient and robust optimization methodology for stress and shape
control of actuated geometrically nonlinear elastic structures, applied to 3D trusses. The …

The present study aims to develop an original solid-like shell element for large deformation
analysis of hyperelastic shell structures in the context of isogeometric analysis (IGA). The …

Numerical simulation based on FEM/IGA methods is the standard approach for the
approximated solution of applied physical problems. In this context, the differentiation of the …
