Abstract A BCMO-ANN algorithm for vibration and buckling optimization of functionally
graded porous (FGP) microplates is proposed in this paper. The theory is based on a unified …

The paper presents an application of the extended Refined Zigzag Theory (eRZT) in
conjunction with the Ritz method to the analysis of bending, free vibration and buckling of …

By using high-order deformation theory, this paper presents a novel approach for analysing
the mechanical behaviours of functionally graded porous beams resting on a Winkler …

Ritz method runs into difficulties when dealing with complex geometry domain due to the
difficulty of constructing a global trial function to approximate structural deformation and the …

Advances in microfabrication technology have enabled micromechanical systems (MEMS)
to become a core component in a manifold of applications. For many of these applications …

This research proposes a Chebyshev–Ritz solution for analysing the size-dependent
behaviour of porous microbeams. The displacement field is based on the higher-order beam …

In this paper insights are provided into the implementation and use of the Ritz method for
free vibration and buckling analysis of composite plates. Focus is given on the choice of the …

A novel variable stiffness optimization (VSO) algorithm is proposed accounting for the
inherent mechanical characteristics of variable angle tow (VAT) plates. Through sampling in …

Buckling of axially functionally graded and nonuniform Timoshenko beams is examined
based on the nonlocal Timoshenko beam theory. Small scale effect on the buckling is taken …

A new numerical method in application to the plate problem is suggested. It starts from
consideration of the rectangular elements, each operating by 6 beam-like parameters: four …
