The unified gradient elasticity theory with applications to nano-mechanics of torsion is
examined. The Reissner stationary variational principle is invoked to detect the differential …

For the first time, this paper introduces a Fast Analysis and Prediction (FAP) approach for
geometrically nonlinear bending analysis of plates and shells. The proposed approach …

This work proposes a new 4-node non-conforming plate element for static and dynamic
analyses of small-scale orthotropic thin plates within the consistent couple stress theory. By …

In the last few years, the corresponding author and colleagues proposed a type of
symplectic analytical singular elements (SASEs) for various crack problems, such as cracks …

Poroelastic materials are essential to engineers to improve the sound and vibration
properties of a product. The most common mathematical model that describes the vibro …

A novel, local and frequency-dependent absorbing boundary condition for unsaturated
porous media is presented. It relates the far-field tractions and displacements produced by a …

Bender elements are shear wave transducers, used for the computation of small strain shear
moduli of geomaterials. However, the distortion of the output signal caused by residual …

In this paper the formulation of hybrid-Trefftz displacement finite elements for transient
problems in three-dimensional elastic media is derived. The mathematical model is derived …

Since the late 80's the Structural Analysis Research Group of the Instituto Superior Técnico
(IST) has been involved in the development of non-conventional finite element formulations …

The hybrid‐Trefftz displacement element formulation for poroelastodyamics in three‐
dimensional saturated media is presented in this article. The governing equations are …
